Abstract Details


To present the use of the point spread function (PSF) metric pre- and postoperatively for the assessment of visual quality in cataract patients with advanced technology intraocular lenses.


TOBB ETU Hospital


Cases with aspheric monofocal, toric and multifocal ALCON SN platform lenses were implanted with standard microcoaxial surgical technique. All PSF measurements were obtained using the NIDEK OPD-Scan II. All eyes underwent corneal topography, wavefront aberrometry, autorefraction, keratometry, and pupillometry measurements pre- and 72 hours postoperatively using the OPD-Scan II. The PSF was used to assess visual quality.


29 cases of cataract surgery, including aspheric intraocular lens (IOL) implantation, diffractive IOLs, and toric IOL implantation, and the difference in PSF are presented.


Point Spread Function is a very reliable indicator of good functional vision. FINANCIAL DISCLOSURE?: No
