Corneal cut closure using temperature-controlled CO2 laser soldering system.

We aimed to evaluate the effectiveness of temperature-controlled laser soldering for repair of large perforated corneas in a porcine model. Eight Yorkshire pigs aged 6 months underwent 6-mm-deep 180° crescent-shaped trephination of the central corneas. Right corneal injuries were repaired by placement of 47 % bovine albumin along the cut followed by CO2 laser soldering (power density 16 W/cm(2)) to a target temperature of 65(°).

CO₂ laser welding of corneal cuts with albumin solder using radiometric temperature control.

Purpose: To examine the efficacy and reproducibility of CO₂ laser soldering of corneal cuts using real-time infrared fiber-optic radiometric control of tissue temperature in bovine eyes (in vitro) and to evaluate the duration of this procedure in rabbit eyes (in vivo).

Methods: In vitro experiment: a 6-mm central perforating cut was induced in 40 fresh bovine eyes and sealed with a CO₂ laser, with or without albumin soldering, following placement of a single approximating nylon suture. A fiber-optic radiometric temperature control system for the CO₂ laser was used.

Effect of pterygium surgery on corneal topography: a prospective study.

Objective: To evaluate the effect of pterygium surgery on the corneal topography and visual acuity and to correlate the results with patients' features.

Methods: A prospective, nonrandomized, self-controlled trial. Computerized videokeratography was performed in 54 patients (55 eyes) with primary pterygium before and after pterygium excision using bare sclera technique combined with intraoperative mitomycin C.

Intraoperative mitomycin C 0.02% for pterygium: effect of duration of application on recurrence rate.

Purpose: To compare the effect of a 3- and 5-minute intraoperative application of topical mitomycin C 0.02% on the recurrence of pterygium.

Methods: A comparative, prospective clinical design was used.

Posterior chamber intraocular lens implantation after capsular tear: ultrasound biomicroscopy evaluation.

Purpose: To evaluate by ultrasound biomicroscopy (UBM) the exact position of a posterior chamber intraocular lens (PC IOL) implanted above a posterior capsule tear and to correlate the findings with the outcomes and complication rate.

Setting: Department of Ophthalmology, Rabin Medical Center, Petah Tiqva, Israel.

Methods: In a retrospective noncomparative case series, 36 patients (36 eyes) who had extracapsular cataract extraction (ECCE) complicated by capsular tear were evaluated.
