Pupil ovalization after phakic intraocular lens implantation is associated with sectorial iris hypoperfusion.

Objective: To investigate iris perfusion in patients with and without pupil ovalization after phakic intraocular lens implantation.

Methods: Comparative retrospective randomized case series of 6 participants, each with a regular pupil, and 6 participants with pupil ovalization after phakic intraocular lens implantation for high myopia were included in the study. Indocyanine green angiography was performed between 20 and 40 months (mean +/- SD, 26 +/- 6.

Keratopathy after ultraviolet B phototherapy.

Atopic dermatitis is the most common chronic inflammatory skin disease among children in industrialized countries. The prevalence is recorded to be up to 20% in children. Phototherapy with ultraviolet B (UVB) is an effective form of treatment with a low complication rate.

Influence of donor storage time on corneal allograft survival.

Purpose: To investigate the influence of graft storage time on corneal allograft survival in high-risk and low-risk patients.

Design: Comparative retrospective nonrandomized clinical trial.

Participants: Overall, 193 patients with 210 corneal allografts were classified as high risk or low risk for corneal allograft rejection on the basis of recipient corneal neovascularization and number of ipsilateral transplants.

Phototherapeutic keratectomy with an epithelial flap for recurrent erosion syndrome.

Phototherapeutic keratectomy (PTK) is an acceptable technique to treat recurrent erosion syndrome. Its disadvantage is postoperative pain. We present a modified technique to reduce the immediate pain from removal of the epithelium after PTK.
