Keratoconus Management With ICL and Toric ICL Posterior Chamber Phakic IOL
Narrative Responses:
Purpose
To analyse the efficiency , ,stability, and predictability of ICL and Toric ICL phakic intraocular lens (pIOL) implantation to correct myopia and astigmatism in eyes with keratoconus.
Methods
This prospective study comprised 32 keratoconic eyes that had implantation of a ICL and Toric ICL. Uncorrected (UDVA) and corrected (CDVA) distance visual acuities, refraction, and postoperative complications were evaluated 1week,2 and 6 months postoperatively.
Results
Preoperatively, the mean spherical equivalent in the 32 eyes was - 5.28±2.06 diopters (D), (range -9 to -2.75 D) and the mean cylinder, -3.14±1.36 D (range -6.50 to 1.25 D). At 6 months, 94.6% of the eyes were within ± 1.0 D of the attempted refraction. For the astigmatic components 63.4% were within ±1.0 D. The mean UDVA was 0.74 ± 0.14 and the mean CDVA, 0.74±0.27, CDVA was 20/50 or better in 95% of eyes and 20/30 or better in 88% No eyes lost more than 1 lines of CDVA, and 84% gained 1 or more lines.
Conclusion
The results confirm that ICL and toric ICL implantation is a predictable, effective procedure to correct ametropia in eyes with keratoconus. Predictability and stability were achieved early and remained fairly stable up to 6 months.
