optical rehabilitation of the patient with aphakia who cannot tolerate contact lenses present a therapeutic challenge. in the absence of capsular support, anterior chamber lenses have been widely used. on the other hand intraocular lens implantation of scleral sutured posterior chamber intraocular lens during penterating keratoplasty or insufficient iris support is recommended. the purpose of t...
Scleral fixation of intraocular lenses (IOLs) can be performed under the protection of a scleral flap. A variation of this technique uses a scleral tunnel for suture fixation to the eye. Passage of a double-armed suture through the roof of the scleral tunnel with subsequent retrieval of the suture ends through the external incision for tying facilitates scleral fixation. This modification offer...
RATIONALE We report 3 cases of a torn haptic after successful scleral fixation with a hydrophobic acrylic intraocular lens. PATIENT CONCERNS Patients complained of decreased visual acuity about 1 week to 1 month after scleral fixation. DIAGNOSES In all 3 cases, the direction of the damaged haptic correlated with the direction of the pulling force made by the hung suture material. Observatio...
Scleral fixation of intraocular lenses (IOLs) and adjunctive capsular devices can be performed under the protection of a scleral flap. A modification of this technique uses a scleral pocket initiated through a peripheral clear corneal incision. Full-thickness passage of a double-armed suture through the scleral pocket and conjunctiva, with subsequent retrieval of the suture ends through the ext...
Various techniques for scleral fixation of IOL in cases of poor capsular support have been described in past. Sutured scleral fixation of IOLs has been attempted for single piece and toric IOLs also. But this predisposes to various suture releated complications. Sutureless fixation of three piece IOLs with or without glue has gained popularity worldwide. However, odd power lenses and high astig...
purpose: to report the outcomes of combined aniridic intraocular lens (iol) implantation via scleral fixation and penetrating keratoplasty (pkp) in three patients. methods: this study included 3 patients who required pkp and had aniridia and/or aphakia requiring iol implantation. all subjects underwent aniridic iol scleral fixation after vitrectomy and removal of capsular remnants followed by ...
PURPOSE To describe a novel technique for toric intraocular lens (IOL) repositioning and fixation in the absence of adequate capsular support. METHODS Case report and literature review. RESULTS Two cases are presented with scleral fixation of a one-piece toric IOL (SN6AT series; Alcon Laboratories, Inc., Fort Worth, TX). In both cases, toric IOLs initially placed within the capsular bag bec...
We describe a technique that uses a capsular hook to obtain sutureless fibrin glue-assisted transscleral fixation of the capsular bag. The hook passes through a sclerotomy created under a scleral flap and engages the capsulorhexis rim, providing scleral fixation intraoperatively and postoperatively. A standard capsular tension ring expands the capsular fornix. The haptic of the hook is tucked i...
Background: The 1ry indication for scleral fixation of intraocular lenses (IOL) is dislocation as a principal complication of cataract surgery. Inadequate capsular support is the most common cause of IOL dislocation. Other indications include traumatic phakic lens dislocation (cataractous or clear), surgically aphakic eyes or anterior chamber IOL with complications (persistent hyphema, uveitis)...
