METHOD FRO TREATING KERATOCONUS Russian patent published in 2005 - IPC

FIELD: medicine, ophthalmology.

SUBSTANCE: one should make a blind circular incision for the preset depth along the border of recipient's biolense bottom, form a peripheral "pouch" in corneal stroma along external edge of circular incision of 0.5-1.0 mm width, deepithelize patient's cornea within biolense's bottom, put an optically negative biolense manufactured out of donor's cornea onto this bottom to fix it with interrupted sutures and reset biolense's edges into stromal "pouch". During applying fixing sutures one should simultaneously carry out compression of recipient's ectopic cornea through a biolense. The method enables to flatten and decrease refracting corneal power that leads to corneal spreading without any deformation and development of folds in Descemet's membrane.

EFFECT: higher efficiency of therapy.
