Abstract Details

Purpose:

To compare subjective satisfaction and refractive outcomes of 2 groups of patients after LASIK refractive surgery: a single treatment group (group A ) and a retreatment group (group B). To test for a correlation between subjective satisfaction and the need for an enhancement procedure to obtain the expected refractive result.

Setting:

Iris Ophthalmology Clinic, Laval, Quebec, Canada

Methods:

This retrospective study included 200 myopic patients selected according to their date of surgery (2017) using the clinic database. To subjectively evaluate satisfaction, patients answered a questionnaire (sent by email via the Survey Monkey platform) consisting of 8 multiple choice questions related to their satisfaction, dryness symptoms and their need to wear glasses or contact lenses. Four questions were combined to compare the 2 groups in terms of satisfaction. Postoperative ametropias and uncorrected visual acuity (UCVA) at far were computed. The SPSS software was used for statistical analysis. The non-parametric Mann-Whitney U test was used to compare the groups.

Results:

Response rate was 13%. In group B, all patients had a flap re-lift at least 3 months after the initial LASIK. Both groups were similar in term of age (32.08±5.84 years vs 34.1± 6.61 years). The mean postoperative spherical equivalent for the right eye in group A was -0.327 ± 0.387D compare to -0.125± 0.412D after the enhancement in group B. 77% of patients in group A achieved an UCVA of 6/6 or better for the right eye compare to 90% in group B. There was no difference between the 2 groups concerning dryness symptoms or subjective satisfaction (p>0.05).

Conclusions:

The satisfaction level in both groups of patients 3 months after the last refractive procedure is high and similar to the one reported by previous studies. Moreover, the vast majority of patients (100% in group A and 90% in group B) indicated that the surgery was a good choice for them. Further studies should include a longer follow-up period and more patients to better document the differences in level of satisfaction.
