Cataract is the condition where the eye lens loses its transparency and becomes cloudy, and it generally appears with advancing age. In this article, we will answer questions such as What is Cataract?, what are the symptoms of cataract in the eye, and what causes cataract? We will also provide important information about how cataract surgery is performed, what precautions should be taken after cataract surgery, and the risks of cataract surgery… Cataract treatment is performed with eye cataract surgery, and this procedure significantly improves visual quality. Cataract surgery is recommended, especially when vision loss caused by the cataract reaches a level that affects daily life.
What is Cataract?
Cataract is the condition where the eye’s natural lens loses its transparency and becomes cloudy over time. This condition is generally associated with old age, but the question of what causes cataract at a young age is also important; factors such as diabetes, smoking, and excessive sun exposure can also trigger cataract development. Cataract symptoms include blurred vision, fading colors, and difficulty with night vision. Cataract surgery is a generally simple and low-risk procedure performed to remove this clouding. The surgery is performed by removing the opaque lens in the eye and replacing it with an artificial lens. For more information, you can check our Cataract page.
How to Prevent Cataracts?
Preventing cataracts is important for healthy eyes and long-term vision quality. Protecting against the sun’s harmful rays by using UV-protective sunglasses, following a diet rich in antioxidants, and avoiding harmful habits like smoking can reduce the risk of cataracts. Furthermore, regular eye examinations and early diagnosis are effective ways to keep cataract development under control. Healthy lifestyle choices and taking care of eye health can help prevent cataract formation.
- Keeping Diabetes and Hypertension Under Control,
- Having Regular Eye Check-ups,
- Healthy Eating,
- Using Sunglasses,
- Limiting Alcohol and Smoking Consumption,
How Does Cataract Affect Vision?
A cataract eye loses its ability to see clearly due to the clouding of the lens inside the eye. This condition prevents light from entering and focusing on the eye, causing images to appear blurry and colors to look faded. As the cataract progresses, vision becomes difficult in daily activities, and additional problems like double vision may arise. Therefore, early diagnosis and appropriate cataract treatment are critically important to preserve vision quality.
Is Cataract Genetic?
Although cataract is generally associated with age, genetic factors can also play an important role in cataract development. Research indicates that some types of cataracts are more likely to occur in family history. Especially congenital (birth) cataract can occur due to genetic mutations and is generally seen in childhood. However, other types, such as senile cataract seen in adults, can also develop as a result of environmental factors and lifestyle choices. Early diagnosis and appropriate treatment methods for cataract are critically important to prevent vision loss. Therefore, individuals with a family history of cataracts should be more careful about eye health and have regular eye examinations.
Types of Cataract
Cataracts can develop due to various factors and have different types. Each type has specific causes and characteristic features.
| Types of Cataract | Features |
| Senile Cataract | Seen as a natural part of the aging process and mostly affects both eyes. Characterized by the slow opacification of the eye lens and generally seen in individuals over 60 years old. |
| Secondary Cataract | Occurs after cataract surgery with the re-opacification of the capsule behind the lens and is treated with laser therapy. |
| Congenital Cataract | Genetic factors, infections, or toxic substances the mother was exposed to during pregnancy can cause this type of cataract. It can be noticed from birth or during infancy. |
| Traumatic Cataract | Formed by damage to the lens resulting from blows to the eye, or sharp or piercing objects penetrating the eye. Cataract may develop rapidly after trauma or years later. |
| Radiation Cataract | Exposure to types of radiation like X-rays or gamma rays can cause this type of cataract. Radiation cataract may especially be encountered in patients undergoing cancer treatment. |
The symptoms, progression rate, and treatment methods for each type of cataract vary. Early diagnosis and appropriate intervention are vital for preserving visual function.

Cataract Symptoms, What Causes Cataract?
Cataract is a disease that occurs with the clouding of the eye lens over time and can cause vision loss. Although this condition is generally linked to the aging process, various factors can also contribute to cataract formation. Cataract symptoms can progress over time, negatively affecting daily life.
What are the Symptoms of Cataract?
Early and advanced stage symptoms of cataract may vary. Cataract symptoms in the eye include the following:
- Blurred Vision: Decreased visual acuity, noticed especially when reading or doing detailed work.
- Light Sensitivity: Bright lights and sunlight can cause discomfort in the eyes.
- Double Vision: Double or shadowed vision may occur even when looking with one eye.
- Faded Colors: A noticeable pallor in colors and a yellowish tone may be observed.
- Weakening Night Vision: Difficulty seeing in dark environments and when driving at night may be experienced.
- Frequent Changes in Glasses Prescription: The need to frequently change glasses or lenses due to vision problems may be felt.
What Causes Cataract?
The process of cataract formation generally begins with the degradation and opacification of proteins in the eye lens over time. The following factors can be given as answers to the question of what causes cataract:
Exposure to Radiation: Radiation-induced cataracts may develop in patients undergoing radiotherapy.
Aging: The most common cause of cataract is age-related lens degeneration (senile cataract).
Genetic Factors: The risk is higher in individuals with a family history of cataracts.
Sunlight (UV Exposure): The likelihood of cataract formation increases in people exposed to sunlight for long periods.
Diabetes: High blood sugar can damage the eye lens and lead to cataract development.
Long-Term Cortisone Use: Long-term use of steroid-containing medications can negatively affect the eye lens and accelerate cataract formation.
Smoking and Alcohol Consumption: Cigarette smoke and alcohol contribute to cataract development by causing oxidative stress in the eye.
Trauma: Eye injuries can disrupt the lens structure, causing traumatic cataracts.
What Causes Cataract at a Young Age?
Cataract at a young age can occur due to various reasons such as special health conditions, genetic predisposition, or environmental factors. For example, genetic disorders, certain metabolic diseases, or infections contracted in the womb can lead to cataract formation in young people. Medication use, especially long-term cortisone treatment, can increase the risk of cataract at a young age. Furthermore, blows to the eye or radiation exposure can also cause cataract formation in this age group.
What You Need to Know About Cataract Surgery
Cataract surgery is the procedure of removing the cloudy lens of the eye and replacing it with an artificial lens, and it is one of the most frequently performed eye operations worldwide. This surgery is generally performed under local anesthesia, and it is possible for the patient to return home on the same day. The surgical process is generally fast and uncomplicated. The surgery significantly increases vision quality, improving patients’ daily quality of life.
During the surgery, the doctor makes a small incision and uses an ultrasound device to break up the lens. Afterwards, the fragmented lens is removed with vacuum, and a clean, transparent artificial lens is placed in its stead.
After cataract surgery, patients generally enter the recovery process immediately. Most people can return to their normal activities within a few days. However, full recovery and stable vision quality may take a few weeks. Slight pain, itching, or mild blurriness in the eye during the post-operative period is normal and is managed with eye drops prescribed by the doctor.
To reduce the risk of post-operative infection, it is important not to let water contact the eye, not to rub the eyes, and to use the medications recommended by the doctor regularly. Furthermore, attending the follow-up appointments set by the doctor is critically important for the success of the surgery and long-term vision health.
Cataract surgery is an effective and safe treatment method, providing a great improvement in quality of life for most patients. However, as with any surgical intervention, it is important to discuss potential risks and complications in detail with your doctor.
Is Non-Surgical Cataract Treatment Possible?
While non-surgical cataract treatment suggests some methods to slow the progression of cataract, there is no existing method that can completely restore the clarity of the clouded lens. In advanced cataract cases, surgical intervention is usually required to improve vision. In early stages, visual aids like glasses or magnifiers and adequate lighting can help alleviate symptoms. However, the most effective method for fully correcting vision loss caused by cataract is cataract surgery.
Preparation Before Cataract Surgery
Preparation before cataract surgery is an important process for the patient. Firstly, the general health status needs to be evaluated. The internal structure of the eye is examined with a detailed eye examination and various imaging tests performed by the ophthalmologist. On the day of the surgery, it is recommended that the patient fast, restrict fluid intake, and adjust certain medications like blood thinners according to the doctor’s instructions. These preparations are necessary for the surgery to be performed safely and successfully.
Risks of Cataract Surgery
Cataract surgery is a highly successful and common procedure in modern eye surgery, but like any surgical procedure, it carries certain risks. Potential risks of cataract surgery include infection, retinal detachment, intraocular lens dislocation, chronic increase in intraocular pressure, and corneal edema. Although these complications rarely occur, they should be considered due to the nature of the surgical intervention.
The risk of infection can manifest as severe inflammation in the eye after surgery and may present with symptoms such as pain, redness, and severe blurred vision. Such an infection can be treated with strong antibiotics and antifungal medications, but if not intervened early, it can cause severe vision loss.
Retinal detachment is a risk, especially seen in myopic patients, and changes in intraocular pressure during surgery can cause the retinal layer to detach. Retinal detachment requires emergency surgical intervention and can lead to permanent vision loss if left untreated.
Intraocular lens dislocation can occur as a result of the lens being misplaced during surgery or the weakening of intraocular structures. This condition can negatively affect vision quality and cause problems like blurred vision or double vision.
In addition to these complications, conditions such as cystoid macular edema may also be observed after cataract surgery. This condition forms swelling, especially in the macular area, due to fluid accumulation in the eye after surgery, and central vision is impaired.
How Long Does Cataract Surgery Take?
Cataract surgery is a common and generally fast procedure performed in the field of eye health. Generally, the duration of cataract surgery in the hands of an experienced surgeon varies between 15 and 30 minutes. This process may differ depending on the surgical techniques used and the patient’s specific condition
The surgery is generally performed under local anesthesia, and patients can often return home shortly after the operation. During the surgery, the cloudy natural lens is removed and replaced with an artificial lens; phacoemulsification or laser techniques may be used during this procedure.
What Should Be Considered After Cataract Surgery?
There are several important points patients should pay attention to after cataract surgery. Adhering to these recommendations is important to positively affect the recovery process:
- Eye Hygiene and Medication Use: Eye drops recommended by the doctor should be used regularly to prevent eye infections after surgery. Keeping hands clean and not rubbing the eyes will reduce the risk of infection.
- Physical Activities: Heavy physical activities and exercises should be avoided for the first few weeks after surgery. Movements that could increase intraocular pressure should be avoided during this period.
- Contact with Water: It is important not to let water get into the eye in the first few weeks. Activities involving water contact, such as swimming or using a jacuzzi, should be avoided in the first few days after surgery.
- Use of Sunglasses: Eyes may be more sensitive to light than usual after surgery. Using UV-protected sunglasses will protect the eyes and provide comfortable vision.
- Regular Check-ups: Attending regular doctor check-ups after surgery is highly important for monitoring the recovery process and detecting potential complications early.
- Abnormal Symptoms: If abnormal symptoms such as severe pain, vision loss, redness, or swelling in the eye are noticed, a doctor should be consulted immediately.
Paying attention to these recommendations during the post-operative period will accelerate the recovery process and prevent potential complications.
What Happens If I Don’t Have Cataract Surgery?
If cataract surgery is not performed, the cataract can progress, leading to severe vision problems and even permanent vision loss. In untreated cataract cases, the lens in the eye gradually becomes cloudier and more opaque over time, which causes vision to progressively worsen. This progression manifests with symptoms such as light sensitivity, double vision, and faded colors. Untreated cataract is the number one cause of blindness worldwide.
Failure to treat a cataract can pave the way for the development of other eye diseases like glaucoma. Furthermore, advanced cataract cases may require more difficult and risky surgical interventions, which increases the risk of complications. In progressive cases, problems such as the surgery becoming more difficult and the recovery period extending may arise.
Cataract surgery is highly safe and effective when performed using modern eye surgery techniques. Early intervention makes the surgery easier and less risky, so it is important to consult an ophthalmologist immediately when cataract symptoms are noticed.
