  1. Laser-assisted Subepithelial Keratectomy for Anisometopic Amplyopia in Children 1 Year Outcomes William F. Astle, MD, FRCSC, Jamalia Rahmat, MD, April D. Ingram, Peter T. Huang, MD, FRCSC

  2. LASEK FOR ANISOMETROPIC AMBLYOPIA IN CHILDREN: 1-YEAR OUTCOMES Purpose: To assess the refractive, visual acuity, and binocular results of LASEK for anisomyopia, anisohyperopia, and anisoastigmatia in children with various levels of amblyopia secondary to the anisometropic causes.

  3. LASEK FOR ANISOMETROPIC AMBLYOPIA IN CHILDREN: 1-YEAR OUTCOMES Method: • retrospective review of 53 kids with Lasek for anisometropia • 3 groups: Myopia diff >3D Astigmatism diff >1.5D Hyperopia diff >3.5 D) • Follow up for 1 yr at least and refractive status, VA and binocular vision check at 2, 6 and 12/12

  4. LASEK FOR ANISOMETROPIC AMBLYOPIA IN CHILDREN: 1-YEAR OUTCOMES Results: • mean age at treatment was 8.4 yrs (10mts-16 years) • mean preop anisometropic diff was 6.98 D in entire group: 9.48 D in the anisomyopic group, 3.13 D in the anisoastigmatic group 5.50 D in the anisohyperopic group

  5. LASEK FOR ANISOMETROPIC AMBLYOPIA IN CHILDREN: 1-YEAR OUTCOMES Results: • One year after LASEK mean anisometropic difference decreased to 1.8 D 2.43 D 0.74 D 2.33 D • 54% of all eyes were within G1.00 D of the fellow eye; 68% within G2.00 D; 80% were within G3.00 D

  6. LASEK FOR ANISOMETROPIC AMBLYOPIA IN CHILDREN: 1-YEAR OUTCOMES Results: • Preop VA and binocular vision measured in 33 kids. • Postop, 63.6% of kids had an improvement in BCVA and remainder no noted change. • No patient had a reduction in BCVA or a loss in fusional ability after LASEK. • Of 33 kids, 39.4% had positive stereopsis preop and 87.9% 1 year after LASEK.

  7. LASEK FOR ANISOMETROPIC AMBLYOPIA IN CHILDREN: 1-YEAR OUTCOMES Conclusion LASEK is an effective surgical alternative to improve VA in anisometropic kids unable to tolerate conventional methods of treatment or in whom these methods fail.
