LASIK for high anisometropia in adults: case report

To evaluate the efficacy of the laser in situ keratomileusis (LASIK) technique in the reduction of anisometropy in adults, for whom conventional treatment was not successful. A sequence of cases of three eyes of three adult patients, two females and one male, age ranging from 28 and 49 years (average 38.3 years), who underwent LASIK. Two patients were followed up for eighteen months and one for six months. Comparing the corrected visual acuity before surgery with the non-corrected visual acuity after surgery, one eye gained two lines of vision, one eye remained the same and one eye lost one line of vision. All eyes remained without spheric refraction, and astigmatism did not exceed -0.75 D after surgery. There has been an improvement in the symptoms of asthenopia in the three patients. The LASIK technique proved to be efficient in the correction of anisometropy in adults, improving visual accuity and asthenopia complaints, and leading to a similar refraction in both eyes.
