Abstract Details

Purpose:

To compare visual acuitites at far, intermediate and near distances, intraocular lens (IOL) centration and quality of life of two groups of patients bilaterally implanted with the trifocal diffractive IOL (Fine Vision). A test group consisted of patients for whom capsulorhexis has been performed by the femtosecond laser and a control group of patients operated with a standard manual phacoemulsification technique.

Setting:

Department of Ophthalmology, Semmelweis University, Budapest, Hungary

Methods:

Thirty patients with no ocular co-morbidity were included in this prospective randomized study. Group A consisted of 15 patients who received a standard cataract surgery (manual capsulorhexis) with implantation of the trifocal diffractive IOL. Group B is made of 15 patients who received a femtosecond laser cataract surgery (femto-capsulotomy) with implantation of the same trifocal diffractive lens (Fine Vision). Three months postoperatively, monocular and binocluar distance-corrected visual acuity at near (35 cm), intermediate (70 cm) and distance (5 m) in photopic conditions and mesopic conditions, binocular defocus curve, IOL centratiobn and tilt assessed by aberrometry (coma and tilt) are compared using a non-parametric test. Quality of life was also evaluated.

Results:

All cataract surgeries were successful. No statistical difference was found in the distant, intermediate and near visual acuity between the two groups. No statistical difference was found in the defocus curve although a trend seemed to favor femtosecond laser surgery. Tilts were comparable. All patients reported having a good quality of life and high spectacle independence.

Conclusions:

Both surgeries provided satisfactorily and statistically similar visual outcomes although femtosecond laser surgery seems to provide more predictable refractive outcomes.
