Abstract Details

Purpose:

To evaluate the visual and refractive outcome of photorefractive keratectomy in adult patients with anisometropic amblyopia.

Setting:

Ophthalmology Unit of University of Messina, Italy.

Methods:

Sixty two subjects with unilateral anisometropic amblyopia treated with photorefractive keratectomy were enrolled to the study. The patients were divided into 3 groups, accordingly to refractive error. First group included 29 eyes with myopia, the second group was composed by 22 eyes with hyperopia and the third by 11 eyes with high astigmatism. Follow-up was of 12 to 24 months after the treatment. The mean outcome measures were the uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA), refraction and corneal transparency.

Results:

In the first group the UCVA changed from 0,06±0,07 to 0,8±0,22 and the BCVA from 0,52±0,1 to 0,84±0,18. 91,9% of eyes improved their BCVA. No eye lost lines of the BCVA. In the second group the UCVA changed from 0,17±0,14 to 0,8±0,2 and the BCVA from 0,53±0,14 to 0,97±0,07. 87% of eyes improved their BCVA. No eye lost lines of the BCVA. In the third group the UCVA changed from 0,1±0,11 to 0,83±0,23 and the BCVA from 0,48±0,1 to 0,98±0,04. 84% of eyes improved their BCVA of 1 or more lines. 1,61% lost 1 line of the BCVA.

Conclusions:

This study shows as the excimer laser refractive surgery appears to be a safe and efficient procedure in the treatment of anisometropic amblyopia in adults. The adult patients with anisometropic amblyopia may benefit from the refractive treatment and a very good visual and refractive outcome can be expected.
