Transscleral fixation of posterior chamber intraocular lenses

Abstract

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.

Late dislocation of scleral-sutured posterior chamber intraocular lenses

“…6,7,11,16,17,[23][24][25][26][27] Polypropylene is a monofilament polymer composed of propene (CH 2 ZCHCH 3 ) configured as an isotactic crystalline polypropylene stereoisomer. It is used in a variety of healthcare and nonhealthcare related fields.…”

“…After the suture was tied, the knot was rotated into the sclera. 26 In case 2, the IOL had dislocated into the vitreous cavity and was sitting on the inferior retina. After a pars plana vitrectomy, a Sinskey hook was passed through the vitrectomy port and used to grasp a portion of the haptic that was not against the retina.…”

“…The inferior haptic remained firmly affixed to the sclera on application of gentle traction, so the superior haptic was resutured to the sclera using a previously described technique. 26 In brief, the old suture was removed and 1 arm of a 9-0 polypropylene suture (Ethicon) was threaded through the eyelet of the free haptic; then, both arms of the suture were passed, 1 at a time, through the limbal incision, through the pupil, and out through the sclera. The IOL was repositioned in the eye while the suture was tightened.…”

“…A new PCIOL (CZ70BD, Alcon) was suture fixated to the superior and inferior sclera, as described previously. 26 In case 4, the IOL had dislocated into the vitreous cavity and was retrieved as described above (case 2). The suture holding the inferior haptic broke free during the surgery, so the IOL was removed through an extended superior limbal incision.…”

Implantation of scleral fixated sutured posterior chamber lenses: a retrospective analysis of 119 cases

“…The scleral fixated intraocular lens is particularly suitable for cases of unilateral aphakia and contact lens incompatibility. The implantation of anterior chamber lenses and their complications can also be avoided [1][2][3][4][5][6][7][8]. In special cases, such as a luxated lens (Fig.…”
