Ultrasound biomicroscopy value in evaluation of restoration of ciliary muscles contractility after cataract extraction.

Purpose: To assess the changes in the contractility of the ciliary muscle in eyes with presbyopia before and after phacoemulsification and intracapsular lens implantation using ultrasound biomicroscopy (UBM).

Patients And Methods: This prospective study included 50 eyes of 30 consecutive subjects operated at the Department of Ophthalmology. Patients with any ocular disorder affecting visual acuity, corneal surface irregularities, had posterior capsular perforation or intensive postoperative corneal edema, or were <35 years of age, were excluded.

Efficacy of transepithelial corneal collagen crosslinking for keratoconus: 12-month follow-up.

Purpose: To evaluate the efficacy of transepithelial corneal collagen crosslinking (TE-CXL) in patients with progressive keratoconus.

Patients And Methods: This is a prospective interventional consecutive study carried out on 30 eyes of 18 patients with progressive keratoconus who underwent TE-CLX using both ParaCel™ (riboflavin 0.25%, hydroxy propyl methyl cellulose, NaCl, ethylenediaminetetraacetic acid [EDTA], Tris, and benzalkonium chloride) and vibeX-Xtra (riboflavin 0.
