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.

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.

Cystoid macular edema after cataract surgery with intraocular vancomycin.

Objective: To determine whether the use of supplemental prophylactic vancomycin in the irrigating solution during extracapsular lens extraction is associated with increased incidence of cystoid macular edema.

Design: Prospective, randomized, double-masked clinical study.

Participants: Consecutive series of 118 patients 60 years of age or older undergoing cataract surgery.
