Preretinal hemorrhages were created in rabbits by perforating Bruch's membrane with a high intensity krypton burn. Bull Mem Soc Fr Ophtalmol. The air-cooled krypton ion lasers of 15- to 200-mW output power have blue emission lines at 468, 476, and 482 nm, green lines at 520 and 531 nm, a yellow line at 568 nm, and red lines at 647 and 676 nm. After an average follow-up of five months, these patients had an average drop of intraocular pressure of 8.9 mm Hg.

Although krypton ion lasers are similar in operation to argon ion lasers, the krypton ion has a wider range of visible emission wavelengths. In summary, the use of ophthalmic lasers has become very common place in the surgical care of many eye disorders and in the case of a cloudy capsule can clear vision and in the case of other disorders can preserve sight.

In this procedure, a patient who has had previous cataract surgery may have subsequent cloudy vision due to clouding of the posterior capsule (so called after cataract or secondary cataract). Krypton passed through the inner retinal hemorrhage without causing damage and created a burn at the level of the retinal pigment epithelium and inner choroid. After an average follow-up of more than five months in these eight patients, the average drop of IOP was 7.2 mm Hg in the eyes with krypton laser trabeculoplasty and 6.8 mm Hg in the eyes with argon laser trabeculoplasty.
