Comparability of the Retinomax K-plus 3 handheld autorefractometer in quick mode versus on-table autorefractometer in standard mode.

INTRODUCTION: This study analyzes the comparability of measurements taken by a Retinomax K-plus 3 handheld autorefractometer in Quick mode and a Topcon KR-800 on-table autorefractometer in standard mode on the pediatric population, and establishes their correlation. METHODS: It is a retrospective comparative study. Spherical diopter power (SPH), cylindrical diopter power (CYL), angle of cylindrical axis (AX), and spherical equivalent (SE) were measured with the Retinomax in Quick mode and with the Topcon in standard mode. Each patient was evaluated in cycloplegic and non-cycloplegic conditions by both autorefractometers. Student's t-test was performed between the two instruments for SPH, CYL, and SE. The Pearson correlation coefficient was calculated and the dispersion was represented using Bland-Altman graphs, also evaluating the subgroup of patients under 4 years of age. A descriptive analysis of the percentages of measures that differed was performed. RESULTS: It included 98 eyes of 49 subjects (age range: 3-16 years). The data for HPS without cycloplegia are virtually identical, whereas with cycloplegia there is a hyperopic bias of +0.5 diopters measured with Retinomax. CYL results are very similar with and without cycloplegia. There is a high Pearson correlation for both instruments (>0.91) and a low degree of dispersion in the Bland-Altman plots under cycloplegia. CONCLUSION: The Retinomax data were consistent with those obtained by Topcon. The Retinomax is a useful instrument for detecting refractive errors in children between 3 and 16 years of age.

[Macular translocation in myopic patient wearing a phakic intraocular lens]. / Translocación macular en paciente miope portador de lente fáquica intraocular.

UNLABELLED: PURPOSE/MATERIAL AND METHOD: To report a case of macular translocation surgery in a myopic patient with a phakic intraocular lens, which developed subfoveal choroidal neovascularization. RESULTS: A 45 year-old woman wearing a phakic intraocular lens to correct a high myopia presented a 0.3 visual acuity because of subfoveal choroidal neovascularization. Peripheral retina had been treated by argon laser for lattice degeneration. Limited macular translocation was performed. Chorioscleral infolding was created by a circular scleral buckle. Her visual acuity, six months after surgery became 0.7. CONCLUSION: This report shows the feasibility of the use of limited macular translocation for the management of high myopic eyes with phakic intraocular lenses, in patients who suffer from subfoveal choroidal neovascularization.
