Abstract

In phacoemulsification-based cataract surgery, a corneal incision is made and is then closed by hydration of the wound lips, or by suturing. We developed a system for sealing such an incision by soldering with a semiconductor disk laser (λ=1.9μm), under close temperature control. The goal was to obtain stronger and more watertight adhesion. The system was tested on incisions in the corneas of 15 eyes of pigs, in-vivo. Optical Coherent Tomography (OCT) and histopathologic examination showed little thermal damage and good apposition. The measured average burst pressure was 1000±30mmHg. In the future, this method wound may replace suturing of corneal wounds, including in traumatic corneal laceration and corneal transplantation.
