Abstract

|
|
Background and Objectives : The continuous curvilinear capsulorhexis (CCC) technique has many advantages, but it is a difficult technique to master. A femtosecond laser system for cataract surgery offers greater precision and reproducibility in opening the anterior capsule than the manual method. The proposed simple femtosecond laser system for CCC can be widely used, compared with the conventional system, due to its compact size and costeffectiveness.
Materials and Methods : Ex vivo testing of the designed simple optical system for CCC in porcine eyes was performed. A laser irradiated the porcine eyes with a 10 μm spot size and energy of 10 μJ.
Results : CCC was successfully performed for diameters of 5 mm, 5.5 mm, and 6 mm by a newly designed simple optical system. Sliding the anterior capsule with tweezers to confirm the quality of the incision showed that the operation was successful.
Conclusion : Compact and simple laser system showed to have good performance. As shown, CCC can be be widely adopted for its precision and low cost.
