Abstract Details


despite the modern intraocular lens (IOL) formulae, the accuracy of IOL power prediction for the cataract eyes receiving corneal refractive surgery is still poor. The aim of this study is to evaluate the visual outcomes in eyes with light adjustable lens (LAL) IOL after previous keratorefractive surgery.


CIMO, Sevilla, Spain


in this cohort study, 22 eyes of 11 patients with cataract and previous keratorefractive surgery (Radial Keratotomy (RK), Photorefractive Keratectomy (PRK) or Laser in situ Keratomileusis (LASIK)) were evaluated. After small-incision bimanual phacoemulsification technique and implantation of the LAL, adjustment and lock-in procedures were completed. The manifest refraction, uncorrected distance visual acuity (UDVA) and corrected distance visual acuity (CDVA) were measured 1, 6 and 12 months after lock-in.


1 month after lock-in, 19 (86%) of the 22 eyes studied were within +/-0.50 diopter (D) of the intended refractive outcome and 15 (68%) were within +/-0.25 D. Mean refractive spherical equivalent (MRSE) was 0.95 D +/- 0.65 (SD) before adjustment and 0.07 D +/-0.42 (SD) at 1 month. 19 (86%) of the 22 eyes achieved +/- 0.50 D of the targeted cylindrical adjustment at 1 month. 20 (91%) of eyes gained 2 or more lines of CDVA. Results remained stable at 12 months.


The LAL is an efficient, predictable and stable method of treating cataract in eyes with previous keratorefractive surgery with the potential to reduce or eliminate postoperative refractive surprises. FINANCIAL DISCLOSURE?: No
