What are Cataracts?
A cataract is a loss of transparency, or cloudiness, of the crystalline lens behind the iris, which under normal conditions focuses the images on the retina.
Toric Intraocular Lenses
These lenses are used in patients with cataracts or who require glasses for far vision (myopia or hyperopia) and near (tired eyesight or presbyopia) who will undergo cataract surgery in both eyes in a short time.
Today there are various types of multifocal lenses. Trifocal lenses can correct far, intermediate and near vision so that patients after surgery do not need glasses for the vast majority of their daily activities with the added advantage that they can use the computer with greater comfort.
Most patients do not require glasses to perform 90% of their activities (for example, the newspaper, a restaurant menu, or the yellow pages). Toric lenses are used in patients with cataracts who have astigmatism and want to correct it during surgery.
Key Points Summary
- Common Eye Condition: Cataracts are a prevalent eye condition, characterized by clouding of the eye's natural lens, leading to decreased vision.
- Symptoms: Common symptoms include blurry vision, difficulty seeing at night, sensitivity to light, and seeing halos around lights.
- Risk Factors: Age is the primary risk factor, but other factors include diabetes, smoking, prolonged exposure to sunlight, and certain medications.
- Diagnosis: Cataracts are diagnosed through a comprehensive eye examination, including visual acuity tests and a slit-lamp examination.
- Treatment Options: Early stages may be managed with glasses or stronger lighting; however, surgery is the most effective treatment for advanced cataracts.
- Surgical Procedure: Cataract surgery involves removing the cloudy lens and replacing it with an artificial intraocular lens (IOL), typically performed as an outpatient procedure.
- Improved Vision: Post-surgery, most patients experience significantly improved vision and a quick recovery, enhancing overall quality of life.
