Argon and YAG laser in the treatment of corneal neovascularization

SUMMARY

Corneal neovascularization (CN) is a major risk factor for corneal graft rejection. Many forms of treatment have been suggested including steroids, irradiation, thiotepa, cyclocriotherapy and others.

Lasertherapy for CN, using Argon and YAG laser, is a new modality of treatment, that it is told to be safe and effective, improving penetrating keratoplasty results. In this paper, we compare two forms of treatment for CN using Argon and YAG laser to access their safety and effectiveness in a randomized study.

In our study, Argon laser has shown being an effective alternative and/or complementary therapy in the treatment of refractory CN. Patients treated with Argon laser had statistically significant improvement of the analyzed parameters (improvement of the neovascularization per quadrant and decrease of the corneal lipid deposition), compared to the group treated with YAG laser (x2 =14.87).
