Surgeon Reports Experience With Intracor At ESCRS Meeting

A significant improvement in near UCVA, slight improvement in distance UCVA, and stable BCVA were noted at 12-month follow-up in 21 patients who underwent presbyopic correction with IntraCOR (Technolas Perfect Vision GmbH, Munich, Germany). Results were promising, with minimal side effects, said Mark Tomalla, MD, during his presentation at the European Society of Cataract and Refractive Surgeons' Winter Meeting in Budapest, Hungary.1

All patients had mild hyperopic presbyopia, with preoperative sphere and cylinder ranging from 0.46 to 0.61 D and -0.23 to 0.25 D, respectively. Patients returned for follow-up at 1 day, 1 week, 1 month, 3 months, 6 months, and 12 months. All patients (mean age 53.8 ±6.2 years) were available for 3- month follow-up; 19 were available at 6 months and 20 at 12 months. On average, patients gained 4.8 lines of near UCVA (logMAR). Although one patient lost 2 lines at 12 months, the majority (60%) gained up to 3 lines of distance BCVA. Distance UCVA remained the same or improved in 75% of patients, and less than 20% lost 2 lines due to a slight myopic shift after IntraCOR. Distance UCVA showed a trend of slight improvement after 12 months.

Dr. Tomalla and colleagues at the Clinic Niederrhein in Duisburg, Germany, used Scheimpflug corneal topography to study the true net refractive power change. The total difference in postoperative minus preoperative refractive power was approximately 2.00 D in the central cornea (Figure 1).
