Objective: Up to now only bioptics could be used in refractive surgery for correcting high muyopia, hyperopia or presbyopia in combination with astigmatisms. Since summer 2007 the first model of a toric dirffractive bifocal intraocular lens is available for correcting combined refractive errors. We present our first results on six eyes of four patients.
Methods: On six eyes of 4 patients (age: 25.57 years) refractive lens exchange with implantation of a toric diffractive multifocal lens (Acri.LISA toric, Fa. Zeiss/*Acritec) was operated. Preoperatively best corrected visual acuity varied between 0.5 and 1.0. In detail preoperative refractive errors of the six eyes were the following: +6.0cc-5.75/60°; -15.75cc-4.5/0°; -15.75cc-5.5/20°; -6.5cc-3.0/6°; -5.0cc-3.25/0°; -4.25cc-4.0/17°.
Results: Postoperatively uncorrected visual acuity varied between 0.5 and 1.25. In detail postoperative refraction was the following: +1.0cc-0.75/35°; +1.5cc-0.75/105°; +1.0sph; +0.5cc-0.75/30°; +0.5cc-0.5/50°; +0.5sph. Refraction was stable also after six months. Patients’ satisfaction was very high.
Conclusions: The new toric multifocal is a new option within refractive surgery. Our first results are very promising. Further results and a comparison to bioptics procedure have to be awaited.
