System for modification of visual acuity by thermal means |
abstract |
A thermo-keratoplasty system and method for locally heating and reshaping a cornea in a manner that produces a minimal regression of the corneal correction. The system includes a probe (12) that is coupled to a power source (14) which can provide a predetermined power, frequency and time duration that creates a thermal profile within the cornea which extends from the epithelium into the corneal stroma. The electrical return of the probe is a lid speculum (202) which maintains the eyelids in an open position. The probe (12) is placed into contact with the cornea and energy is transferred from the power source (14) to the eye, through the lid speculum (202) and back to the power source (14). The energy from the power supply is focused by a probe tip (240) that locally heats and denatures the cornea, and causes a subsequent shrinkage of corneal tissue. A pattern of denatured areas can be created around the cornea to correct the vision of the eye. |
