TO EVALUATE THE SAFETY , EFFICACY AND PREDICTABILITY OF FEMTOSECOND LASER (LENSAR) ENABLED ARCUATE INCISIONS FOR THE CORRECTION OF PREOPERATIVE TOPOGRAPHIC ASTIGMATISM AT THE TIME OF CATARACT SURGERY

Phacoemulsification is the gold standard for cataract surgery. With constant improvements and continuous upgradations, most of the modern phacoemulsification systems on the market have improved on safety and efficacy, leading to reduced surgical times and lower rates of intra-operative complications, translating into better postoperative outcomes and patient satisfaction. Surgical efficiency, however, may vary, depending upon the surgeon’s skills as well as the machine settings. A good clinical outcome depends on the combination of both.

In line with these advancements, a new femtosecond laser system “LENSAR†has been recently updated to correct the topographic pre-operative astigmatism by arcuate incisions. The system has a unique ability to mark the arcuate incision on the cornea with the inbuilt woodcock nomogram, the reference image can directly be transferred to the LENSAR from the Pentacam, or if old versions of Pentacam are used it can also be transferred through an external hard disk, the device also has a unique ability to auto correct the cyclorotation by iris identification software after the patient is in supine position to maximize the results.
