Purpose: To assess the safety and efficiency of bimanual phakoemulsification through two 1.2 mm paracentesis and implantation of an foldable hydrophilic intraocular lens. Moreover the practicability of a new combined Irrigation/ Chopper handpiece is investigated.
Method: Prospective interventional clinical trial consecutively included 20 patients who underwent cataract surgery through two 1.2 mm paracentesis performed by one surgeon. For Implantation of an AcriLys IOL (Acritec) one paracentesis was enlarged to 1.6 - 1.8 mm. (Handling of the handpiece and parameter of the phakomachine are shown in a video).
Results: Phakoemusification through two 1.2 mm paracentesis was possible in all patients with no major intraoperative complications. Postoperative visual acuity was 0.91 ± 0.18, intraocular pressure 17.4 ± 0.24 and induced astigmatism 0.39 ± 0.20 dpt. The IOL remained centrated in a follow-up period of 8.1 ± 3.4 month. In 3 patients the implantation procedure had to be repeated to a rupture of the shooter cartridge which occurred in paracentesis smaller than 1.6 mm width.
Conclusions: Minimal incisional cataract surgery through a 1.8 mm paracentesis with a combined irrigation/chopper handpiece seems to be a safe and efficient procedure with a minimal induced corneal astigmatism.
