Abstract Details

Purpose:

To assess efficacy, safety, predictability, and stability after clear lens extraction (CLE) with multifocal diffractive intraocular lens (IOL) implantation.

Setting:

INSTITIONAL

Methods:

Prospective, nonrandomized, masked observational case series (self-controlled). Five hundred eyes of 1000 consecutive patients underwent CLE with bilateral zeiss trifocal IOL implantation. Eyes were divided into myopic (mean spherical equivalent [SE], -6.01+/-2.71 diopters [D]) and hyperopic (mean SE, +3.86+/-2.52 D) groups.Monocular and binocular uncorrected distance visual acuity (VA), best-corrected distance VA, uncorrected distance near VA, and best distance-corrected near VA were recorded preoperatively and 6 months after surgery

Results:

At 6 months postoperatively,uncorrected distance VA was 20/25 or better in 100% of the eyes. Efficacy indexes(EI) were 0.97 for myopic and 0.96 for hyperopic patients.Safety indexes were 1.05 for myopic & 1.02 for hyperopic patients.All eyes were within +/-1.00 D of the desired refraction for the hyperopic group,8 eyes lost 1 or 2 lines, 20 eyes gained 1 line, and 16 eyes gained 2 lines. Safety indexes at near were 1.05 for myopic and 1.11 for hyperopic patients. Uncorrected near VA was better for hyperopic than myopic patients .EI at near were 1.03 for myopic and 1.10 for hyperopic

Conclusions:

Clear lens extraction with TRIFOCAL IOL implantation is an effective procedure for correcting ametropia and presbyopia. Safety and efficacy indexes at distance were comparable in myopic and hyperopic patients. However, at near, both indexes were larger for hyperopic patients
