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 bilateral cataracts, or who require eyeglasses for both far and near vision that will need cataract surgery in both eyes within a short time. This type of lens can correct both near and far vision so that after surgery patients will not require eyeglasses for the majority of their activities. Approximately 90% do not require either far vision or near reading glasses to read the newspaper, a restaurant menu or even a phonebook. There are multiple types of multifocal lenses in todayâs market. Multifocal lenses can be divided into BIFOCAL and TRIFOCAL lenses. Bifocal lenses allow near (reading and handheld devices such as a phone) and distance vision (more than a yard in distance). Trifocal lenses allow near, intermediate (computer) and distance vision.
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.
