Implication

Prospective comparative study reveals equivalent optical quality and intraocular scattering in eyes after phakic lens implantation, indicating visual outcomes matching healthy eyes.

Key Points

To evaluate optical quality and intraocular scattering in eyes following posterior chamber phakic intraocular lens implantation compared with healthy normal eyes.
Prospectively evaluated 38 eyes of 19 consecutive patients undergoing implantable contact lens (ICL) implantation (mean age 36.3 ± 5.7 years) and 38 age-matched eyes of 19 healthy volunteers (mean age 36.4 ± 4.9 years).
Quantitatively measured modulation transfer function (MTF) cutoff frequency, Strehl ratio, objective scattering index (OSI), and Optical Quality Analysis System values (OVs at 100%, 20%, and 9% contrast) at 3 months postoperatively.
At 3 months post-implantation, ICL eyes achieved a mean MTF cutoff frequency of 28.69 ± 8.59 cycles/degree, Strehl ratio of 0.17 ± 0.04, OSI of 1.06 ± 0.48, and OV at 100% of 0.96 ± 0.29.
Differences between the ICL and control groups were not statistically significant for MTF cutoff frequency (P = 0.31), Strehl ratio (P = 0.46), OSI (P = 0.30), OV 100% (P = 0.51), OV 20% (P = 0.46), or OV 9% (P = 0.36).
