AIM: To assess subjective and objective parameters of visual function after implantation of the AcrySof ReSTOR in amblyopic patients.
METHODS: Phacoemulsification and IOL implantation were performed in six eyes of three patients with anisometropic amblyopia. Patients were examined after 16-18 months for uncorrected and distance-corrected visual acuity (VA) for distance, intermediate and near. A defocus curve, the extent of crowding, contrast sensitivity and stereo acuity were recorded.
RESULTS: The mean age of the patients was 56 years (range 53-60). In the non-amblyopic eye, the uncorrected distance VA was 20/25 or better, and the best corrected distance VA was 20/20 or better; in the amblyopic eye, the VA was two to four lines worse. The near VA of the non-amblyopic and the amblyopic eye was equivalent to the distance VA. The defocus curve showed a clear bifocal profile, even in the amblyopic eye. Stereo acuity was found in the Titmus test but not in the random dot tests (Lang-chart and TNO test). All patients had a crowding phenomenon in the amblyopic eye. Binocular contrast sensitivity was within normal limits. Photic phenomena were not reported by any patient, and none of the patients required glasses for any distance, resulting in a high patient satisfaction.
CONCLUSION: Anisometropic amblyopic patients may benefit from implantation of an AcrySof ReSTOR; no unwanted side effects were detected.
