Lens Fragmentation

Cataract is a leading cause of blindness in the world, and cataract extraction is one of the most commonly performed surgeries. Preferred surgical techniques have changed over the past decades with associated improvements in outcomes and safety. Phacoemulsification is a highly successful technique first introduced over 40 years ago. It is the current method of cataract surgery, with a very low reported rate of major complications and a frequency of overall intraoperative complications of less than 2%. Application of the femtosecond laser evolved to now assist in cataract surgery and has been termed FLACS (femtosecond laser-assisted cataract surgery) and occurs in three steps: corneal incisions (including optional limbal relaxing incisions to reduce astigmatism), anterior capsulotomy, and lens fragmentation. The remaining surgical steps still require the surgeon’s hands. The FLACS technique may have some advantages compared with conventional phacoemulsification. It remains however unclear whether FLACS is globally more efficient and safer than conventional surgery. The popularity of FLACS may also be limited by its higher cost compared with conventional surgery. The potential advantages of laser-assisted surgery are yet to be determined as FLACS technology is relatively new and in continuous evolution. This chapter reports scientific data as well as our own experience with this new technology. All the platforms currently available are described.

AbstractStudying anterior lens capsule cutting edge profiles from femtosecond laser-assisted capsulotomy procedures performed before and after lens fragmentation. Twenty eyes (10 patients) with age-related cataract underwent femtosecond laser-assisted surgery (FLACS) using the Ziemer Z8 platform. First step of laser surgery was either capsulotomy (group first) or fragmentation (group second). One eye of each patient was assigned randomly, the second eye treated with the different sequence of procedures. After anterior capsule removal, tissue was fixed in cacodylate-buffered solution and cutting-edge profiles were analysed using scanning electron microscopy (SEM). All cases had cataract grade 2 and 3 based on LOCS III grading. SEM analysis showed more smooth edges in the first group, especially in cases with pseudoexfoliation (P = 0.037); more tags and bridges and a significant number of staggered cutting patterns (7 out of 10 cases) in the second group. All cases evolved the same microgroves with “valleys and mountains “ as signs of the photodisruption process. Femtosecond laser capsulotomy should be performed before lens fragmentation minimizing the rate of cutting errors. Especially in eyes with advanced cataract, as intracapsular pressure may increase due to lens fragmentation without anterior capsular opening.
