PURPOSE: To describe a technique for implanting capsular hooks made from a 7-0 polypropylene sutures, used for sutureless scleral fixation of the capsular bag in cases of lens subluxation.
METHODS: A 26-G needle was used to guide the 7-0 polypropylene suture into the eye. The suture was then extracted and thermally shaped into a hook. A needle holder clamped the built-in suture needle, allowing it to pass through the superficial layer of the sclera at the puncture site. Both hands coordinated the subsequent procedure: The suture was pulled externally, while the hook was advanced internally to vertically engage with the capsular bag at the site of continuous curvilinear capsulorhexis.
RESULTS: This technique was applied to 11 eyes of 11 patients. The best-corrected visual acuity improved from a preoperative mean of 1.15 ± 0.39 logarithm of the minimum angle of resolution [logMAR] (Snellen 20/206) to 0.18 ± 0.15 logMAR (Snellen 20/29) at the final follow-up. Throughout the follow-up period, the capsular hook exerted stable vertical traction on the capsular bag at the site of the continuous curvilinear capsulorhexis without slippage.
CONCLUSION: The capsular hooks made from 7-0 polypropylene sutures provide an effective alternative method for stabilizing the capsular bag in cases of moderate to severe lens subluxation.
