Transscleral fixation of posterior chamber intraocular lenses.

In a retrospective study of 75 consecutive eyes having transscleral suturing of a posterior chamber intraocular lens (IOL) (mean follow-up five months), 57% had improved best corrected visual acuity; 67% of those obtained a visual acuity of 20/40 or better. Thirty-seven eyes had an IOL exchange without penetrating keratoplasty (PKP) at the time of implantation, 15 had simultaneous PKP, and 23 had secondary lens implantation without IOL exchange or a corneal transplant. Transscleral fixation is an effective means of implanting a posterior chamber lens in eyes without capsular support. It allows secure two-point lens fixation with minimal risk of IOL tilting or suture erosion through the conjunctiva or sclera.
