Age‐induced change in the color of the human crystalline lens
Purpose To determine the chromatic coordinates of different human crystalline lenses to analyze the age-induced change in the color of the crystalline. Methods The spectral transmission of nine human crystalline lenses of different ages were measured by using a Perkin-Elmer 800 UV/VIS spectrophotometer. Using these data we calculated the chromatic coordinates of each crystalline lens for both solar and incandescent illumination. The study adheres to the tenets of the Declaration of Helsinki for Research Including Human Subjects and was approved by the Institutional Review Board. Results The results show a greater saturation of color with the increase of age. In principle, the change tends t…
Light transmission of the human lens and its relation with aging
Purpose To determine the visible light transmission of the human crystalline lens of persons of different ages, using both solar and incandescent illumination. Methods The spectral transmission of lens was measured by using the Perkin-Elmer 800 UV/VIS spectrophotometer. With these data we calculated the percentage of visible light transmission for solar illumination, simulated by the CIE D65 illuminant, and for incandescent illumination (A illuminant). Results The total amount of visible light transmitted by nine crystalline lenses is represented as a function of age: with solar illumination and with incandescent illumination and the comparison between both illuminants.In general, the amoun…
Customized intraocular telescope implanted in high myopic patients with advanced maculopathy
Purpose To evaluate the results of intraocular personalized telescope implantation to improve distance best corrected visual acuity (BCVA) in high myopic patients having cataract surgery. Methods This prospective non randomized observational study included 16 eyes of 9 consecutive patients with advanced maculopathy associate to high myopia having cataract surgery. Bilateral implantation of the intraocular telescope was performed after phacoemulsification in patients having the requisites. The telescope consists of two lenses a positive high power lens is implanted in the anterior chamber and a negative one is implanted in the posterior chamber. The lenses power, magnification and residual r…
