Abstract
To evaluate the feasibility of piggyback insertion with a toric Implantable Collamer Lens (ICL, STAAR Surgical).
This study investigated eight pseudophakic eyes of five patients who underwent piggyback insertion of a toric ICL to correct residual refractive error. Uncorrected distance visual acuity...

Abstract
Twenty eyes of 20 patients ranging in age from 24 to 48 years old were evaluated. The anterior chamber depth increased significantly with pupil dilation (mean change 0.06 mm +/- 0.08 [SD]) (P<.01). A significant change was also observed in the distance between the center of the cornea at the endothe...

Abstract
Results indicate that AC pIOL implantation can be considered an alternative modality to manage clinically significant, severe anisometropic myopia in pediatric eyes when there is poor patient compliance with traditional medical treatment. Long-term follow-up of corneal endothelial cell density after...

The majority of those treated have anisometropic amblyopia. The most common method employed is advanced surface ablation using the excimer laser, such as photorefractive keratectomy or laser-assisted subepithelial keratomileusis. Surface ablation is safe in children; the drawback is the high rate of...
