Iris Repair

Patients with aniridia or damaged irises can suffer from severe light sensitivity and are often unhappy with the appearance of their eyes. Also, a damaged iris admitting too much light can result in reduced vision, halo and glare. Iris repair often involves the use of sutures inside the eye to reshape the iris to its original shape, re-creating a round pupil. Sometimes the surgeon may cut some of the existing iris to help improve the appearance.

Capsular rupture is a dreaded complication of cataract surgery; it jeopardises the chances of inserting a posterior lens and therefore obtaining the ideal optical correction of the patient's aphakia after the operation. However, if this complication does occur, do not panic: most cases can be salvaged. Anterior subcapsular cataract results from fibrous metaplasia of the lens epithelium.

Loose zonules complicate cataract surgery because their laxity makes removal of the nucleus and cortex challenging and limits stability of the IOL. In some patients we are able to detect zonular laxity during the preoperative consultation. Even in cases without visually significant cataract, subluxation of the lens can occur due to zonular damage and prompt the need for surgical intervention.

Atlantoaxial subluxation is usually asymptomatic but may cause vague neck pain, occipital headache, or occasionally intermittent (and potentially fatal) cervical spinal cord compression. You might need surgery if you have repeated episodes of subluxation. Your surgeon can fix any problems that are making your shoulder joint unstable. This includes: ligament tears.
