Purpose:
To report photorefractive keratectomy and LASIK for the correction of myopia in eyes with congenital nystagmus.
Methods:
Photorefractive keratectomy was performed in one eye and LASIK performed in eight eyes of five adult patients (three men and two women) with congenital nystagmus. Mean patient age was 34 years.
Results:
Preoperative refraction ranged between -1.50 and -22.00 diopters (D) sphere, and -0.50 and -3.25 D of astigmatism; best spectacle-corrected visual acuity (BSCVA) ranged between 2 m finger counting and 20/30. In all nine eyes, postoperative uncorrected visual acuity (UCVA) equaled or exceeded preoperative BSCVA. Postoperative topography showed central ablations. Results were stable at follow-up 18 months after surgery, except in one eye with follow-up of 4 months. Enhancement was not required in any eye.
Conclusions:
Positive results were achieved for ablation performed with a broad beam laser in eyes with nystagmus.
