This study analyzed intraocular lens (IOL) power calculations using the SRK formula, finding most eyes had minor deviations. Accuracy improved for eyes with normal axial lengths.

Area of Science:

  • Ophthalmology
  • Biomedical Engineering

Context:

  • Postoperative refractive outcomes after cataract surgery.
  • Intraocular lens (IOL) power calculation accuracy.

Purpose:

  • To evaluate the dioptric deviation of emmetropic IOLs from SRK formula calculations.
  • To identify factors influencing IOL power calculation accuracy.

Summary:

  • Investigated postoperative dioptric deviation from SRK formula calculations for intraocular lenses.
  • 82% of eyes showed deviations within +/- 1.5 D.
  • Normal axial length eyes (22.0-24.5 mm) yielded more accurate calculations.
  • Discussed factors influencing SRK formula accuracy and postoperative refraction.

Impact:
