phakic posterior chamber lenses for high myopia functional and anatomical outcomes purpose to evaluate the functional and the anatomical outcomes after implantation of phakic posterior chamber intraocular lenses iols in highly myopic eyessetting service dophtalmologie hpital purpan toulouse francemethods fiftyeight eyes of 46 patients that had implantation of phakic posterior chamber lenses for high myopia were evaluated predictability efficiency safety and subjective and objective quality of vision were evaluated preoperatively and at least 6 months postoperatively the effect of the procedure on the cornea aqueous humor pupil anterior chamber angle crystalline lens and retina were studiedresults mean preoperative myopia was 1385 diopters d 31 sd range 800 to 1925 d mean postoperative spherical equivalent was 122 083 d range 075 to 350 d 569 of eyes were within 100 d of the predicted result and 776 gained 1 or more lines of best corrected visual acuity all contactlensintolerant patients had improved quality of vision for day and night driving distance vision and vision under dim illumination the mean postoperative level of contrast sensitivity without correction was higher than the mean preoperative level with correction adverse events were 2 cases of crystalline lens opacification 16 and 18 months after surgery and 2 cases of pigment deposits in the angle with increased intraocular pressure which was controlled by betablockersconclusion implantation of posterior chamber phakic iols is effective and predictable however longterm followup is needed
