The Zero CDE (cumulative dissipated energy) technique facilitates cataract removal with no or minimal phaco energy. This is facilitated by a femtosecond laser, which pre-divides the cataractous lens nucleus into multiple small segments that can be aspirated without phaco energy being delivered to the eye. In the investigator's experience, this technique consistently shows a stable anterior chamber, a low complication rate, and a rapid return of vision following cataract surgery. This prospective study aims to document the outcomes with the zero CDE technique during femtosecond laser-assisted cataract surgery (FLACS).

In this single-arm, non-comparative study, patients with cataract grade 1-3 (LOCS III nuclear sclerosis) will undergo cataract removal with the Zero CDE technique that involves no or minimal phaco energy. This is facilitated by a femtosecond laser, which pre-divides the cataractous lens nucleus into multiple small segments that can be aspirated without phaco energy being delivered to the eye.
