228 LASER IN OPHTHALMOLOGY
Retinal and choroidal hemorrhage is caused by the acoustic and shock waves generated by optical breakdown very close to retinal surface. Usually choroidal and retinal hemorrhages clear within four weeks. If during laser procedure choroidal hemorrhage is detected, pressure on the globe by the laser contact lens will stop it spontaneously.
2.Retinal hole formation and retinal detachment.
3.Cataract formation (in phakic eyes): The suggested laser focus behind the posterior capsule to avoid this complication is 4 mm.
4.Implant damage (in Pseudophakic eyes).
5.Vitreous hemorrhage: Posterior vitreolysis of an untreated vascularised membrane or band causes vitreous hemorrhage.
6.Vitritis.
