Influence of tomographic and biomechanical corneal indexes on myopic refractive surgery indications: A multicenter study.

Purpose: To evaluate the influence of corneal tomographic and biomechanical indexes on the refractive technique indication.

Methods: A total of 251 eyes from 251 patients interested in refractive surgery were enrolled in this cross-sectional and multicenter study. Previous to the surgeon decision, a preoperative protocol was performed by refractive optometrists, containing four sections: refraction, biometry, corneal tomography and biomechanics.

Postoperative optical aberrations in eyes implanted with AcrySof spherical and aspheric intraocular lenses.

Purpose: To evaluate and compare optical and visual quality of eyes implanted with spherical and aspheric intraocular lenses (IOLs).

Methods: Twenty eyes of 17 patients were implanted with the AcrySof Natural IQ aspheric IOL (SN60WF) and 20 eyes of 15 patients were implanted with the AcrySof Natural spherical IOL (SN60AT). Photopic monocular distance best spectacle-corrected visual acuity (BSCVA) was recorded at 6 months postoperatively.
