Results of intraocular lens power calculation were lower than actual required power in eyes with previous corneal refractive surgery because the inaccurate readings of corneal power obtained from standard keratometry. This causes the unacceptable hyperopia after cataract surgery. With increasing of population undergone excimer laser refractive surgery, this problem will be an obvious problem in...

PURPOSE A seventh annual survey was carried out by mail in February 1999 to investigate the current trends in cataract and refractive surgery in Japan. METHODS Questionnaires were sent to 925 ophthalmologist members of the Japanese Society of Cataract and Refractive Surgery. Data received from 411 (44.4%) of the recipients were cross-analyzed and compared with those from the previous surveys....

Refractive outcomes following cataract surgery in patients that have previously undergone laser refractive surgery have traditionally been underwhelming. This is related to several key issues including the preoperative assessment (keratometry) and intraocular lens power calculations. Peer-reviewed literature is overwhelmed by the influx of methodology to manipulate the corneal or intraocular le...

PURPOSE To demonstrate the use of the Quality of Life Impact of Refractive Correction (QIRC) questionnaire for comparing the quality of life of pre-presbyopic individuals with refractive correction by spectacles, contact lenses, or refractive surgery. METHODS The 20-item QIRC questionnaire was administered to 104 spectacle wearers, 104 contact lens wearers, and 104 individuals who had undergo...

purpose: to report the refractive changes after intraocular lens (iol) implantation in children with congenital and developmental cataract. methods: in this historical cohort study, the clinical records of children between 2 and 15 years old that had lensectomy with posterior capsulotomy, anterior vitrectomy and iol implantation with more than 5 years of follow-up were studied. refractive error...

the porcine eye is often used as an ex vivo animal model in ophthalmological research. it is well-suited for investigations concerning refractive surgery; however, corneal topography data are scarce. this study investigated the corneal topography and pachymetry of the porcine eye to provide further reproducible data. we evaluated freshly enucleated porcine eyes (n = 16) by performing computeriz...
