Cataract is a common eye disease that causes blurred vision due to the loss of transparency in the lens of the eye over time. Although it is more common in older ages, it can also occur at younger ages due to factors such as diabetes, eye trauma, long-term corticosteroid use, and genetic predisposition. With the technologies used in cataract treatment today, patients can experience a safer, more comfortable, and faster recovery process.
What is Cataract?
Cataract occurs when the transparent structure of the lens is lost. It can cause symptoms such as blurred vision, sensitivity to light, decreased night vision, and faded color perception by preventing light from reaching the retina in a healthy way. Since the disease usually progresses slowly, symptoms increase over time.
Cataract Symptoms
The most common symptoms include blurred vision, double vision, difficulty driving at night, glare from bright lights, frequent changes in eyeglass prescriptions, and faded color vision. When these symptoms begin to affect daily life, an eye specialist should be consulted.
Cataract Causes
Advanced age is the most significant risk factor. In addition, diabetes, smoking, prolonged exposure to ultraviolet radiation, eye injuries, certain medications, and genetic factors can also accelerate the development of cataract. Regular eye exams are crucial for early diagnosis.
Recent Developments in Cataract Treatment
The definitive treatment of cataract is surgery. In modern methods applied today, the cloudy natural lens is removed and replaced with an artificial intraocular lens. Phacoemulsification technique is applied with small incisions and provides rapid healing. Femtosecond laser-assisted surgery can offer more sensitive stages in certain patients. Additionally, with single-focus, toric, and multifocal intraocular lens options, both cataract treatment and some refractive errors can be corrected.
Surgical Procedure
Cataract surgery is usually performed under local anesthesia and is of short duration. Most patients can return home on the same day. Regular use of the doctor's recommended drops and follow-up exams are important for the recovery process.
Post-Operative Precautions
In the first days, it is necessary not to rub the eye, not to lift heavy objects, to pay attention to hygiene rules, and to use the prescribed medications regularly. Visual quality usually improves rapidly, but full recovery may vary from person to person.
Can Cataract be Prevented?
While not all cataract cases can be prevented, using UV-protected sunglasses, avoiding smoking, controlling diabetes, eating a balanced diet, and having regular eye exams can contribute to reducing the risk.
Frequently Asked Questions
Is Cataract Treated with Medication?
No. There is no medication that can completely eliminate cataract today. Effective treatment is surgical.
How Long Does Cataract Surgery Take?
The surgery usually takes between 15-30 minutes. The time spent in the hospital may be longer due to preparation and rest.
Is the Surgery Painful?
Generally, since local anesthesia is applied, patients do not feel significant pain.
How is the Intraocular Lens Chosen?
Lens selection is determined based on eye structure, lifestyle, existing refractive errors, and doctor's evaluation.
Can Cataract Recur?
The removed natural lens does not grow back. However, in some patients, clouding may develop in the posterior capsule, and this condition can be treated with laser application.
