Abstract

Minimal Incisional Phakoemulsification

Sauder G., Degenring R., Jonas J. B.
University Eye Hospital Mannheim Faculty for clinical medicine of the Ruprecht Karls University Heidelberg

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.
