Abstract Details

Purpose:

To assess visual outcomes after treatment of residual refraction in patients with a multifocal intraocular lens implanted using manual arcuate keratotomy (AK) or laser vision correction (laser in situ keratomileusis [LASIK] or photorefractive keratectomy [PRK]).

Setting:

Cl�nica Baviera, AIER Hospital Group. Spain

Methods:

This retrospective clinical study was based on 1884 eyes with low mixed astigmatism after implantation of a multifocal intraocular lens (IOL) in both eyes. Previous treatment was with refractive lens exchange or cataract surgery (509 patients were treated with excimer laser [bioptics group] and 866 patients with manual AK). Outcome measures included preoperative and postoperative uncorrected distance acuity (UDVA), corrected distance visual acuity (CDVA), and subjective patient visual satisfaction.

Results:

Mean UDVA, improved from logMAR 0.2 � 0.08 to 0.05 � 0.04 in the bioptics group and from 0.17 � 0.08 to 0.06 � 0.05 in the AK group. Differences before and after surgery in the bioptics and AK groups were as follows: mean absolute subjective cylinder, decrease from �1.24 � 0.38 diopters (D) to �0.22 � 0.23 D and from �1.09 � 0.28 D to �0.39 � 0.3 D (p < 0.01); mean CDVA 0.04 � 0.04 to 0.03 � 0.04 and 0.04 � 0.03 to 0.04 � 0.04 R (p = 0.137). No statistically signi?cant differences were recorded.

Conclusions:

Manual AK was effective and safe at reducing refractive error in patients with residual astigmatism after implantation of a multifocal IOL. Visual outcome and subjective satisfaction were comparable to those of laser vision correction.
