ESCRS: New Phakic Refractive Lens Promises Accurate Refractive Correction By Ana Hidalgo-Simón, MD Special to DG News BARCELONA, SPAIN -- January 28, 2002 -- Preliminary results of an European multicentre study with PRL, a new type of refractive ocular lens for the correction of both high myopia and high hyperopia, show that it is effective in correcting refractive errors with an acceptable complication rate. The results were presented January 25th at the 6th ESCRS (European Society of Cataracts and Refractive Surgeons) refractive surgery meeting in Barcelona, Spain. The multicentre study aims to recruit 220 implants in 11 eye centres all over Europe. Bo Philipson, MD, from the Stockholm Eye Institute, Sophiahemmet, Stockholm, Sweden presented the results of the study so far. The new lens, an improvement of earlier intraocular lens models, is characterized by a high flexibility, high refractive index and a very thin structure. Its optical diameter is between 4.5 to 5 mm depending on the power. The ease of implantation is one of its main assets, says Philipson. Investigators have currently performed 100 implantations with the new model. "Although the follow-up is still short, the target versus achieved refractive error results are very promising", Dr Philipson said. "Around 80% of patients had a post-implantation visual acuity spherical equivalent within 1 dioptre of target, which was beyond our expectation." The complications rate observed has also been good: "We observed an increase in the intraocular pressure in 8% of patients, but it was a mild and transitory effect. Also 8% of patients had glare or halos, but it was not clinically significant". They had one case with significant bleeding from the iridectomy, which is part of the implantation procedure. "These results look very promising so far. The power calculations are instantly being improved, and we need a longer follow-up to assess the efficacy of the lens", he concluded. The European multicentre study is sponsored by CIBA Vision and Medennium. E-mail this page to a friend or colleague! To print, use this version
