Study finds, Adjunctive Green Thermal Laser Photocoagulation
A Study was conducted to investigate the safety and efficacy of green thermal laser as an adjunctive therapy for the treatment of resistant infectious keratitis (IK).

A retrospective case series of 150 patients, within a 4 year duration, with resistant IK, who failed to respond to specific medical treatment alone for 7 days, were included. They all received green thermal laser photocoagulation treatment to the cornea as an adjunctive to medical treatment.

--48 women and 102 men were included in this study with a mean age of 46.2 ± 7.7 years.

--Common risk factors associated with IK included trauma by material of plant origin and contact lens wear.

--The mean duration of healing was 2.87 ± 0.7 weeks. A single session of green thermal laser application was adequate in 138 IK cases (92%), while 12 cases (8%) required an additional session a week later.

--Supplementary amniotic membrane transplantation (AMT) was required in 26 cases. 2 patients required tectonic keratoplasty for corneal perforation.

--The final corrected distance visual acuity (CDVA) was counting fingers (CF) or better in 78 patients (52%). No decrease of CDVA was reported throughout the study.

Conclusively, Green thermal laser is a safe and effective adjunctive therapy for the treatment of resistant infectious keratitis.
