Laser thermal keratoplasty
- Laser thermal keratoplasty
Laser thermal keratoplasty is a non-contact laser refractive surgery.[cite journal |author=Ariyasu RG, Sand B, Menefee R, "et al" |title=Holmium laser thermal keratoplasty of 10 poorly sighted eyes |journal=Journal of refractive surgery (Thorofare, N.J. : 1995) |volume=11 |issue=5 |pages=358–65 |year=1995 |pmid=8528914 |doi=] ][cite journal |author=Haw WW, Manche EE |title=Conductive keratoplasty and laser thermal keratoplasty |journal=International ophthalmology clinics |volume=42 |issue=4 |pages=99–106 |year=2002 |pmid=12409925 |doi=] ]Procedure
The procedure employs a holmium laser to place a ring of concentric laser burns on the cornea between 6mm and 7mm in diameter. These burns cause a ring of constriction on the peripheral cornea causing the cornea to steepen making the eye focus better at near. This procedure may regress somewhat over time. It is similar to the CK (conductive keratoplasty)procedure where a micro-needle high frequency probe is used to make a ring of corneal burns in a similar fashion.
