Intraocular lens calculation for aspheric intraocular lenses.
PURPOSE To evaluate the possible benefits of biometry and ray-tracing intraocular lens (IOL) calculation for aspheric aberration-correcting IOLs. SETTING Private eye clinic in Germany. DESIGN Retrospective consecutive case series. METHODS Eyes with 3 different aberration-correcting IOLs were reviewed. Before surgery, the axial length, corneal thickness, anterior chamber depth, crystalline...
متن کاملAspheric glass lens modeling and machining
The incorporation of aspheric lenses in complex lens system can provide significant image quality improvement, reduction of the number of lens elements, smaller size, and lower weight. Recently, it has become practical to manufacture aspheric glass lenses using diamond-grinding methods. The evolution of the manufacturing technology is discussed for a specific aspheric glass lens. When a prototy...
متن کاملPatient-Reported Difference following Implantation of a Blue Light-Filtering Aspheric Intraocular Lens and a UV-Filtering Aspheric Intraocular Lens
We report on a series of 6 patients who experienced yellow vision after uncomplicated cataract surgery in their second eye. In the first eye, an aspheric blue-light filtering intraocular lens (IOL) was implanted, followed by the implantation of a 1-Piece aspheric IOL in the second eye. The time between the surgeries ranged from 12 months to 3 years. The patients experienced noticeable differenc...
متن کاملThe efficiency of aspheric intraocular lens according to biometric measurements
PURPOSE To analyze internal spherical aberration in pseudophakic eyes that underwent aspheric intraocular lens (IOL) implantation, and to investigate the relationships between biometric data and the effectiveness of aspheric IOL implantation. METHODS This retrospective study included 40 eyes of 40 patients who underwent implantation of an IOL having a negative spherical aberration of -0.20 μm...
متن کاملAspheric intraocular lens selection: the evolution of refractive cataract surgery.
In the current era of presbyopia-correcting intraocular lenses (IOLs), toric IOLs and aspheric IOL technology, the practice milieu is changing. Informed consent takes on newmeaning when the surgeon and the patient decide together which IOL technology represents the best fit for a particular life style and its visual demands. Customizing IOL choice is no longer optional; it is essential to the p...
