Abstract

Purpose:

To evaluate the visual performance of different types of intraocular lens (IOL) in eyes submitted to femtosecond laser (FSL) cataract surgery and to analyze whether this technology could result in spectacles independence.

Design:

Retrospective comparative case series.

Methods:

Consecutive eyes that were scheduled for FSL cataract surgery were included in this study. After one month postoperative, patients were divided into two groups: cases that required prescription for eyeglasses and cases that did not require prescription. In addition, the patients were analyzed according to the type of IOL that was implanted (monofocal, monofocal toric, multifocal and multifocal toric).

Results:

Thirty-five cataract surgeries were analyzed. Twenty-three eyes had a monofocal IOL implanted, and 12 had a multifocal IOL implanted. After 1 month, 12 cases required prescription (Group 1), and 23 did not require prescription (Group 2). The proportion of eyes that did not require corrective lenses was significantly greater (P = 0.02) in eyes that received multifocal IOL (91.67%) compared with those that received monofocal IOL (47.83%). Additionally, 100% of eyes that received multifocal toric IOL did not require eyeglasses at one month postoperatively.

Conclusion:

The FSL surgical precision associated with modern IOL technology may be an important factor related to vision satisfaction after cataract surgery.
