Capsular phimosis
Progressive contraction of the anterior capsule opening following cataract surgery, potentially affecting IOL position.
Full Definition
Capsular phimosis refers to the progressive constriction of the anterior capsular opening (capsulorrhexis) following cataract extraction. This complication can occur weeks to months after surgery due to fibroblastic proliferation and contraction of capsular remnants. The condition may cause IOL decentration, visual field defects, or decreased visual acuity. Surgical documentation should note the degree of constriction, any associated IOL movement, and treatment options such as Nd:YAG laser capsulotomy or surgical revision. Risk factors include certain IOL designs, surgical technique variations, and patient-specific healing responses.
Usage
Usage note: Distinguish carefully from posterior capsule opacification in postoperative documentation.
