Abstract Details


To evaluate the efficacy and postoperative complications of the femtosecond laser cataract surgery in Japanese eyes, including the utility of the recently developed smaller suction cup and the reduction of phaco-energy during PEA.


Nishi Eye Hospital


79 eyes with senile cataract underwent cataract surgery, in which the processing of CCC and lens fragmentation were done by femtosecond laser treatment (Catalys, OptiMedica). Efforts were made to reduce unnecessary phaco-energy during PEA.


In 2 among 79 cases, CCC was partially not completed due to anterior subcapsular cataract. 2 cases led to rupture of posterior capsule. In 15 cases, only the IA procedure was necessary after lens fragmentation for removing the whole cataract. The cataract grade ranged from N2 to N4 and IA time ranged from 2 to 8minutes. In 1 case with hypermature cataract, CCC was possible but lens fragmentation was not completed, leading to ECCE. The updated sample size, outcomes and complications will be reported.


The outcomes may not differ dramatically from those by classic cataract surgery. The laser-made imperfect CCC, even just partially might make posterior capsule rather fragile. On one hand, the current efficacy to complete the whole cataract surgery procedures using this technology is definitely the future issue to be solved. On the other hand, this technology has a great potential to improve the standard learning curve of cataract surgery, by effectively reducing phaco-energy and even eliminating the needs of the whole PEA procedure for cataract surgery. The smaller suction cup should be beneficial in paediatric cataract surgery.
