Penetrating limbal relaxing incision

Yin-hui Yu, Ke Yao
As the leading cause of blindness, the type of surgery performed to remove cataracts has evolved from Intracapsular to Extracapsular and to phacoemulsification. Advantages of femtosecond laser include high instantaneous power, strong penetration, short pulse-duration and micro-precision present superior accuracy, predictability and safety to cataract surgery, while also minimizing injury to surrounding ocular tissue. It mainly assists in the procedures of anterior capsulotomy, lens fragmentation, clear corneal incision and limbal relaxing incision creation...

PURPOSE: We modified the deep anterior lamellar keratoplasty big bubble technique to improve safety and ease of performance. METHODS: We describe a modification of the big bubble technique that involves injecting the air bubble through a peripheral corneal incision 1 mm from the limbus. The incision is made with a limbal relaxing incision knife. This is done before trephination of the recipient cornea, hence the name "early bubble." The goal of this technique is to reduce the risk of intraoperative corneal perforation and to obtain a large air bubble between Descemet membrane and the corneal stroma...

PURPOSE: To present the outcome of photorefractive keratectomy (PRK) using a new neodymium:YAG (Nd:YAG) laser in patients with irregular astigmatism. SETTING: Claremont Eye Clinic, Claremont, and the University of Western Australia, Perth, Australia. METHODS: In 3 patients with irregular astigmatism, PRK was performed with a solid-state, 213 nm wavelength, 300 Hz scanning-spot, diode-pumped Nd:YAG ablative laser (CustomVis Pulzar laser system)...
