Abstract Details

Purpose:

To subjectively evaluate Femtosecond Laser-assisted intracorneal ring segment (ICRS) implantation on quality of vision of patients with keratoconus and to identify factors responsible.

Setting:

Department of Ophthalmology ,Faculty of Medicine Alexandria University, Egypt

Methods:

This study was conducted on 30 eyes of 30 patients with keratoconus who received the Kera rings. The femtosecond laser (Visumax ,Carl Zeiss Meditec,Inc., Duplin, CA) was used for tunnel creation. Patients were examined for uncorrected visual acuity (UCVA), best-corrected visual acuity (BCVA), and manifest preoperatively the operation and 1 and 3 months postoperatively. A specially designed questionnaire was answered by the patients at least 3 months after surgery. The questions were designed to measure the satisfaction of patients after receiving the ICRs.

Results:

The mean uncorrected visual acuity was 0.1 ± 0.08 preoperatively and 0.48 ± 0.19 three months or more postoperatively. This difference was statistically significant (P= 0.002). The mean score for clarity of vision in general was 3.6 ± 0.9 (1 = extremely unsatisfied, 5 = very satisfied). The mean score for night vision was 2.8 ± 0.7. The mean score for far vision was 2.7 ± 1.1. Fluctuation of vision was present in 53% of patients. Night glare and halos were complained of in 88% and 82% of patients respectively.

Conclusions:

In spite of the significant improvement in uncorrected visual acuity and the average overall satisfaction with vision after femtosecond-assisted intracorneal segment implantation in keratoconus patients, a significant number of patients were dissatisfied with night vision.
