“…Rabbit Corneas: Light and Transmission Electron Microscopy Corneal responses immediately and 24 hours following LTK at 9.0 J/cm2, as seen by LM and TEM, consisted of marked stromal swelling in the anterior and posterior region in a similar configuration as seen in the 762 human specimens, alterations in stromal matrix, and epithelial, keratocytic, and endothelial damage (Fig 5A). The laser effects appeared more pronounced in the 10.9-J/cm2 specimens.…”

“…The ocular effects of infrared energy, such as from the CO 2 (wavelength, 10.6/xm) or Nd:YAG (1.06/zm) lasers, have been studied previously in the roles of a cutting knife (CO 2 laser) [2,3,7,8,11,12], a coagulating device or a photodisruptive tool (Nd:YAG laser) [1,5,14,19]. The CO 2 laser incisions are accompanied by a heavy coagulative reaction [3,7,[11][12][13]. Recently, Seiler and associates [18] and Loertscher and co-workers [9] have reported on corneal effects of another infrared wave- r length-producing system, the hydrogen fluoride laser (wavelength, 2.7 to 3/xm).…”

We evaluated the effects of the erbium:YAG laser (2.9 micron wavelength) on ocular structures. Energy was successfully transmitted through a fiberoptic bundle for intraocular and extraocular applications. The wavelength was strongly absorbed by ocular tissues, producing ablations with minimal thermal damage. Our results indicated that the erbium:YAG laser may have potential uses as a photoablative tool to reshape the corneal surface and as a surgical knife.

“…Several authors reported success rates of up to 70% using the CO 2 laser for trabeculectomies and trabeculosclerostomies [38,39,40,41,42,43,44]. In 1999, Belkin et al [45] described a non-penetrating trabeculectomy with a CO 2 laser in rabbits with promising results.…”

CO<sub>2</sub>, Excimer and Erbium:YAG Laser in Deep Sclerectomy

et al. 2008

Purpose: Deep sclerectomy is a non-penetrating filtering procedure that is not generally accepted, as tissue dissection is difficult and varying success rates have been reported. The purpose of the present study was to compare the use of CO₂, excimer and erbium:YAG lasers in dissection of the deep corneoscleral lamella. Methods: In enucleated porcine eyes a superficial lamellar scleral flap of 5 × 5 mm was surgically dissected. The deep lamella was removed using a pulsed erbium:YAG, a CO₂ or an excimer laser (10 eyes/group). All eyes were analysed histologically and 3 in each group by scanning electron microscopy (SEM). Results: It is feasible to ablate the deep corneoscleral lamella with the CO₂, excimer and erbium:YAG lasers without perforating the anterior chamber. The following histology and SEM showed a smoother surface after dissection with the CO₂ and excimer lasers compared to the erbium:YAG laser. There was no thermal damage after excimer laser treatment, compared to a damage zone of 10–30 µm using the erbium laser and one of 70–100 µm with the CO₂ laser. Conclusions: Excimer,erbium:YAG and CO₂ lasers allow the microsurgical dissection of the deep lamella. The excimer and CO₂ lasers achieve a more regular and smoother tissue surface. The excimer laser has the advantage to dissect without thermal tissue damage.
