BACKGROUND AND OBJECTIVE
A pilot study was conducted to evaluate the use of a prototype intraocular carbon-coated diode laser probe for performing single-instrument internal retinotomy and retinectomy.
MATERIALS AND METHODS
A 20-gauge endolaser probe was used to perform retinotomies on 10 anesthetized rabbits. Two protocols were examined: one using low power and long duration, and one using high power and short duration. Retinotomies were performed on attached and experimentally detached retinas.
RESULTS
Retinotomies were performed in all eyes using both protocols. The edges had photocoagulative effects in all cases. The eyes treated with the longer duration, lower power protocol had scleral damage, whereas the eyes treated with shorter duration, higher power did not.
CONCLUSION
Although the diode laser coagulator/cutter may be used for retinotomies, it should be studied further.
背景与目的
开展一项试点研究，以评估用于进行单器械视网膜内切开术和视网膜切除术的原型眼内碳涂层二极管激光探头的使用情况。
材料与方法
使用20G内激光探头对10只麻醉兔进行视网膜切开术。研究了两种方案：一种使用低功率和长时间，另一种使用高功率和短时间。在附着的和实验性脱离的视网膜上进行视网膜切开术。
结果
两种方案均在所有眼中成功进行了视网膜切开术。所有病例的边缘均有光凝作用。采用较长时间、较低功率方案治疗的眼睛出现巩膜损伤，而采用较短时间、较高功率方案治疗的眼睛未出现。
结论
尽管二极管激光凝固器/切割器可用于视网膜切开术，但仍需进一步研究。
