Cataract
WHAT IS EYE CATARACT?
- Age related cataract. Seen in patients more than 60 years of age
- Traumatic and foreign body injury
- Metabolic like calcium, phosphorus deficiency
- Exposure to radiation
- Drugs like steroids
- Associated with systemic diseases
Your ophthalmologist can diagnose it using simple OPD tests and procedures
- 1. History of previous illness and medication
- 2. Visual complaints
- 3. Visual Acuity testing
- 4. Visual field testing
- 5. Slit Lamp examination
- 6. Dilated examination
Treatment consists of surgical removal of the cataract (opaque natural lens in eye) and replacing it with an intraocular implant (lens)
- 1. Peribulbar injection
- 2. Subtenons injection
- 3. Topical with anaesthetic drops and/or jelly
The main advantage of topical anaesthesia is reduced hospital stay. There is no added advantage in terms of visual outcome. Topical anaesthesia requires careful patient selection and counselling by the surgeon.
Medical Retina
A cataract is the clouding of normal crystalline lens of the eye. It develops slowly and results in gradual progressive decrease in vision. It may affect one or both eyes.
