Chynn, MD, FACS, MBA, of Park Avenue Laser Vision in New York, told Ocular Surgery News. Such conditions include eyes with severe scarring, corneal edema, ocular trauma or a keratoprosthesis.

Cataract surgery can be complicated by presence of loose zonules

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. Severe laxity may result in subluxation of the cataract or marked phacodonesis, in which the cataract is seen to move or shake in response to ocular movement. Patients with visible pseudoexfoliative material on the anterior lens capsule are also at higher risk for loose zonules. Other signs may be more subtle, such as a (Read more...)
