Abstract
Purpose: The efficacy of two types of contact transscleral Nd:YAG laser delivery systems, a synthetic sapphire-tipped laser probe connected to a Surgical Laser Technologies (SLT) laser and a quartz fiberoptic tip connected to a LASAG Microrupter III, was compared. Method: A total of nine pigmented rabbits underwent transscleral LASAG cycloablation in one eye (3.2 W, 0.5 s); an additional eight rabbits underwent Surgical Laser Technologies cycloablation (3.0 W, 0.5 s). Results: The maximum difference in intraocular pressure between the experimental versus fellow eyes was - 15.09 mm Hg (±0.25) with the LASAG and -13.16 mm Hg (±3.12) with the SLT laser; in both delivery systems, this difference was achieved 4 days postoperatively. The differences between the two groups in duration of pressure reduction was not statistically significant (p = 0.83). Conclusion: These data suggest that these delivery systems are equally effective in lowering intraocular pressure in rabbits. Histological changes of the ciliary processes and adjacent ocular tissue are presented.
