Safety and Efficacy of Current Sclera Fixation Methods for Intraocular Lenses and Literature Overview.

The volume of IOL revision surgery is increasing. Often, the only option left for visual rehabilitation is scleral IOL fixation. All three scleral fixation techniques studied demonstrated a good safety profile with no statistically significant impact on IOP, CMT, CCT, but with a notable revision rate. Visual rehabilitation to preoperative baseline levels (GoreTex [n = 14] and Prolene [n = 19]) and a statistically significant increase in visual acuity (total cohort [n = 55] and Yamane [n = 22]) seems possible. Unlike iris fixation, scleral fixation is surgically more complex and the surgeon must master a steeper learning curve.
