Types of Cataract Surgery
Cataract surgeries differ according to the surgical techniques applied and the types of artificial lenses used. The most frequently preferred types of cataract surgery today are:
Phacoemulsification (Phaco) Method
Phacoemulsification is the most commonly used method in modern cataract surgery. In this technique, the cloudy lens is broken into small pieces and removed by aspiration using a probe that vibrates with ultrasonic waves. Then, an artificial intraocular lens (IOL) is placed into the capsule of the natural lens. Since a small incision is made, it does not require stitches, and the recovery time is fast.
Extracapsular Cataract Extraction (ECCE)
Extracapsular cataract extraction is a method in which a large piece of the lens is removed in a single procedure. Since this technique requires a larger incision, the recovery time is longer compared to phacoemulsification. It is generally preferred in cases of extremely hardened cataracts where phacoemulsification is not suitable.
Intracapsular Cataract Extraction (ICCE)
Intracapsular cataract extraction is an older surgical technique rarely used today. In this method, the lens and the surrounding capsule are completely removed together. It is not preferred in modern surgery due to the high risk of complications and long recovery time.
Femtosecond Laser-Assisted Cataract Surgery (FLACS)
Femtosecond laser-assisted cataract surgery is a method that utilizes laser technology. In this technique, precise incisions are made in the cornea, and the lens is fragmented with the help of a laser. Thanks to the precision provided by the laser, it can offer additional advantages, such as the correction of astigmatism. However, its use is limited due to its higher cost and the fact that it is not suitable for every patient.
During cataract surgery, an artificial intraocular lens (IOL) is placed to replace the removed natural lens. There are also different types of artificial lenses used during cataract surgery. The types of IOLs used are selected according to the patient’s visual needs and eye structure:
Monofocal Lenses
Monofocal IOLs are standard lenses with a single focal length. They are usually set to provide clear distance vision, so patients may need to use glasses for near tasks (like reading).
Multifocal and Trifocal Lenses
Multifocal and trifocal IOLs are designed to provide clear vision at different distances. These lenses can offer better vision at both near and distant ranges, but some patients may experience side effects such as glare at night lights or reduced contrast sensitivity.
Toric Lenses
Toric IOLs are lenses specifically designed to correct astigmatism. These lenses compensate for irregularities in the cornea, providing clearer vision. Toric lenses can be combined with monofocal, multifocal, or trifocal features.
Extended Depth of Focus (EDOF) Lenses
EDOF IOLs are designed to provide seamless vision at intermediate and distant ranges. These lenses offer an advantage, especially in intermediate distance activities like computer use, but an additional need for reading glasses may exist for very near vision.
Accommodative Lenses
Accommodative IOLs aim to increase focusing ability by responding to natural muscle movements inside the eye. These lenses may provide better vision at different distances but may not yield the desired results in every patient.
Cataract Surgery Risks
Cataract surgery, although considered a safe and effective procedure, can involve certain risks and complications, as with any surgical intervention. While these risks are minimized in surgeries performed by experienced eye surgeons, it is important for patients to be informed.
Infection and Inflammation (Endophthalmitis)
Infection of the intraocular tissues, a rare but serious complication. Symptoms of infection and inflammation include severe eye pain, redness, swelling, and vision loss. Treatment requires urgent medical intervention; it is usually treated with the injection of antibiotics or antifungal medications directly into the eye.
Increased Intraocular Pressure (Ocular Hypertension):
A temporary elevation of intraocular pressure after surgery. Symptoms of increased intraocular pressure include eye pain, headache, and blurred vision. In the treatment of increased intraocular pressure, pressure is controlled with eye drops or oral medications.
Retinal Detachment
Separation of the retinal layer from the underlying tissue; a rare but serious condition that can lead to vision loss. Symptoms of retinal detachment include sudden flashes of light, floaters, or a curtain sensation in the field of vision. In the treatment of retinal detachment, the retina is reattached through surgical intervention.
Secondary Cataract (Posterior Capsule Opacification)
Clouding of the back part of the lens capsule after surgery; a common complication. Symptoms of Posterior Capsule Opacification include blurred vision and reduced sight. Treatment involves opening the opaque capsule with a simple and painless procedure called YAG laser capsulotomy.
Intraocular Lens Displacement (Decentration)
Decentration is the condition where the implanted artificial lens shifts or becomes displaced. Symptoms of Decentration include blurred vision, double vision, or reduced visual acuity. Treatment, if necessary, involves surgical repositioning of the lens.
Intraocular Hemorrhage
Definition of Hemorrhage is the accumulation of blood inside the eye during or after surgery. Symptoms of Hemorrhage include reduced vision and redness in the eye. Treatment: small hemorrhages usually resolve spontaneously; large hemorrhages may require surgical intervention.
Corneal Edema (Corneal Swelling)
Definition of Corneal Swelling is the swelling of the corneal layer due to fluid accumulation. Symptoms of Corneal Swelling include blurred or hazy vision. Treatment: Edema usually subsides within a few days; medication is used in severe cases.
Droopy Eyelid (Ptosis)
Definition of Ptosis is the drooping of the upper eyelid. Symptoms of Ptosis include noticeable drooping of the eyelid and restriction of the field of vision. Treatment: in most cases, it resolves spontaneously; if permanent, surgical correction may be needed.
Most of these complications are rare and can be treated effectively with early diagnosis. Following your doctor’s recommendations during the postoperative period and not neglecting regular check-ups minimizes potential risks.

Who is Not Suitable for Cataract Surgery?
In some cases, cataract surgery may not be recommended:
- Advanced Stage Eye Diseases: Advanced stage retinal diseases can negatively affect the success of cataract surgery. For example, the risks of surgery may increase in patients with macular degeneration or severe retinal tears. Complication risk may increase during and after cataract surgery in patients with uncontrolled or advanced stage glaucoma.
- Active Eye Infections: In cases of active infection or inflammation in the eye, surgery must be postponed to prevent the risk of infection spread.
- General Health Problems: Uncontrolled Diabetes or Hypertension like systemic diseases can negatively affect postoperative recovery and increase the risk of complications.
- Patients with Heart Failure or Respiratory Problems may have difficulty lying flat during surgery, which can complicate the surgical procedure.
- Difficulty Lying Flat: For patients who cannot lie flat on their back, cataract surgery may become technically difficult or impossible.
- Insufficient Visual Potential: In patients with optic nerve damage, the expected visual improvement after cataract surgery may not be achieved.
In these situations, your ophthalmologist will conduct a detailed evaluation, weighing the risks and benefits of the surgery. If necessary, the most suitable treatment plan will be determined with additional tests and consultations.
Pre-Operative Care for Cataract Surgery
Patients must pay attention to certain points before cataract surgery:
- Detailed Eye Examination: Before surgery, your ophthalmologist will conduct a comprehensive eye examination to assess the degree of the cataract and the overall health of the eye. This examination is critical for planning the surgery and selecting the appropriate artificial lens.
- Use of Blood Thinning Medications: If you are using blood thinning medications such as aspirin, warfarin, or similar drugs, it is important to inform your doctor. To reduce the risk of bleeding during and after surgery, your doctor may recommend temporarily stopping or adjusting the dosage of these medications.
- Eye Hygiene: Keeping the area around the eye clean before surgery is important to minimize the risk of infection. Your doctor may advise you to use antibiotic eye drops for a specific period before the surgery.
- Fasting Status: Cataract surgeries are generally performed under local anesthesia, and in this case, you may not need to fast. However, general anesthesia may be administered in some special situations. If general anesthesia is planned, you may be asked to fast for a certain period (usually 6-8 hours) before the surgery. You must strictly follow your doctor’s instructions regarding this.
- Arranging a Companion: Your vision may be temporarily blurred after surgery, and this may affect your daily activities. Therefore, it is recommended that you have a companion with you on the day of surgery to accompany you home.
- Wearing Comfortable Clothes: You should choose loose and comfortable clothing for comfort during and after the surgery. Furthermore, it will be beneficial to leave your jewelry and accessories at home or remove them before the surgery.
- Compliance with Doctor’s Instructions: Your ophthalmologist will inform you about the eye drops or medications you need to use before the surgery. Strict compliance with these instructions is critical for the success of the operation and the prevention of complications.
By paying attention to these points before the surgery, you can increase the effectiveness of cataract surgery and make your recovery process more comfortable.
How is Cataract Surgery Performed?
Cataract surgery is a surgical procedure where the cloudy natural eye lens is removed and replaced with an artificial lens. It is generally performed under local anesthesia and takes approximately 15-30 minutes. The basic stages of the surgery are as follows:
- Anesthesia Application: Local Anesthesia: Before the surgery, the eye is numbed via eye drops or injection. This ensures the patient does not feel pain during the procedure and remains awake.
- Creation of a Small Incision: The eye surgeon makes a small incision, approximately 2-3 mm, at the edge of the cornea. This incision is the entry point for surgical instruments and the placement of the artificial lens.
- Removal of the Cloudy Lens: Phacoemulsification Method: Using ultrasonic waves, the natural lens is broken into small pieces and removed by aspiration. This method is minimally invasive and ensures a fast recovery process.
- Implantation of the Artificial Lens: Intraocular Lens (IOL) Implantation: A foldable artificial lens is inserted into the eye through the small incision, replacing the removed lens, and is secured in the natural lens capsule.
- Closure of the Incision: The small incision usually closes spontaneously and does not require stitches. This shortens the recovery period and increases patient comfort.
- Postoperative Care: After the operation, the patient is kept under brief observation and usually discharged the same day. During the recovery period, eye drops recommended by the doctor should be used, and scheduled check-ups should be regularly attended.
Postoperative Care for Cataract Surgery
There are some important points patients need to pay attention to during the postoperative recovery period:
- Avoid Rubbing Eyes and Use Protective Eyewear: Avoid putting pressure on your eyes after surgery. Rubbing the eyes for the first few weeks can damage the surgical area. The use of protective glasses or an eye shield, especially when sleeping at night, can prevent accidental damage to the eyes.
- Regular Use of Medications: Antibiotic and corticosteroid eye drops prescribed by the doctor reduce the risk of infection and control inflammation. Regular use of eye drops as recommended speeds up the recovery process.
- Avoid Heavy Physical Activities: Heavy lifting and bending should be avoided for the first 2 weeks, as these movements can increase intraocular pressure and cause postoperative complications. Running, weightlifting, or intense exercises are not recommended within the first month after surgery.
- Use Sunglasses: Eyes may become more sensitive to light after surgery. The use of UV-protected sunglasses provides comfort and positively affects the healing process.
- Prevent Water Contact: It is important to avoid getting water in the eye for the first week. It is recommended to keep the eyes closed while showering and avoid water-related activities such as swimming and saunas. Pools and jacuzzis should be avoided for at least a few weeks as they can increase the risk of infection.
- Carefully Monitor Symptoms: If any of the following abnormal symptoms occur, a doctor should be consulted immediately:
- Severe pain and discomfort.
- Sudden or increasing vision loss.
- Excessive redness, swelling, or light sensitivity.
- Sudden blurriness or shadows in the eye.
- Serious complications like Retinal Detachment can be successfully treated if diagnosed early.
- Attend Regular Doctor Check-ups. A doctor’s check-up is mandatory within the first week after cataract surgery. Follow-up appointments are critical for monitoring healing and the early diagnosis of potential complications.
Strict adherence to doctor’s recommendations is necessary for a successful recovery process after cataract surgery. Measures such as eye hygiene, avoidance of physical activities, use of medications, and regular check-ups help minimize the risk of complications. If unusual symptoms are noticed after surgery, the ophthalmologist should be contacted without delay.
When Does Vision Improve After Cataract Surgery?
The time it takes for vision to fully improve after Cataract surgery can vary from patient to patient. Generally, it is normal to experience a slight blurriness or haziness immediately after the surgery. This is related to the eye adapting to the new lens and the commencement of the healing process.
- Blurred Vision in the First Few Days: In the first few days after surgery, there may be symptoms such as slight discomfort, redness, and sensitivity to light in the eye. Visual clarity may not be fully achieved during this period. However, a noticeable improvement in vision is usually observed from the second day onward.
- Vision Clearing in the First Week: By the end of the first week, most patients can return to their daily activities and feel a significant increase in the quality of their vision. However, it may take a little more time to achieve full recovery and the best possible vision level.
- Full Recovery is Between 3-6 Weeks: The full recovery process usually ranges between 3 and 6 weeks. During this period, inflammation in the eye decreases, and visual acuity increases. It is important for patients to regularly use the eye drops recommended by their doctors and not neglect their follow-up appointments. Important Notes After Cataract Surgery:
- Individual Differences: Every individual’s recovery process is different. Factors such as pre-existing eye disorders, general health status, and age can affect the recovery time.
- Doctor’s Recommendations: During the postoperative period, adherence to all your doctor’s instructions and regular use of prescribed medications positively influence the recovery process.
- Abnormal Symptoms: If you notice unusual symptoms such as severe pain, sudden vision loss, or excessive redness, you must consult your doctor immediately.
The improvement of vision after cataract surgery is a gradual process and requires patience. By following your doctor’s recommendations and not neglecting your regular check-ups, you can achieve the best results.

Surgical Technique: Phacoemulsification (Phaco) Method is a common method where the cataractous lens is fragmented and removed using ultrasonic waves, and an artificial lens is implanted. Femtosecond Laser-Assisted Cataract Surgery, this method, performed using laser technology, provides more precise incisions and procedures, but may increase the cost.
Hospital or Clinic Selection: In Private Hospitals and Clinics, prices may vary according to the quality of services offered, the technologies used, and the location of the hospital. In State Hospitals, no additional fee may be charged for surgeries performed under the scope of the Social Security Institution (SGK) when standard lenses are used. However, additional costs may apply if a special lens is preferred.
Health Insurance Coverage: SGK may cover standard cataract surgeries and basic lenses. However, special lenses like multifocal or toric are generally not covered by the SGK and may require an additional fee. Private Health Insurances: Depending on the scope of the policy, they may cover a part or the entirety of the surgery. Additional coverage may be required for special lenses and advanced surgical techniques.
Price Ranges: In Private Hospitals, depending on the technology used and the type of lens selected, cataract surgery prices may range between 30,000 TL and 50,000 TL. In State Hospitals, no additional fee may be charged for surgeries performed under the scope of the SGK when standard lenses are used. However, additional costs may apply if a special lens is preferred.
Cataract surgery prices may vary depending on the hospital’s pricing policies, the materials used, and the surgeon’s experience. Therefore, it is recommended that you contact the relevant healthcare institutions directly for current and definite price information.
