Abstract Details

Purpose:

To evaluate the predictability,safety and stability of toric phakic implantable collamer lens implantation to correct moderate to high myopic astigmatism.

Setting:

Eye Specialty Private Hospital,Baghdad,Iraq

Methods:

60 eyes of 40 patients underwent implantation of a toric implantable collamer lens(V4c design).Mean spherical refraction was ₋11.32diopter (D)±3.17(SD)with range from ₋6.00to₋18.00Dand the mean cylinder was-2.61(D) ±1.16 with range from ₋1.00 to ₋5.50D.The outcome measures that evaluated during a 12 months follow-up period include UDVA,refractive outcomes, CDVA, vault and adverse events.

Results:

At 12 months postoperatively the mean Snellen decimal UDVA was 0.77±0.23 and mean CDVA was 0.80±0.21, with an efficacy index 1.16. Twenty nine eyes (48.33%) showed gain in CDVA with safety index 1.21.The treatment was highly predictable for spherical equivalent and astigmatic component .The mean SE dropped from (₋12.63D±3.11) to ( ₋0.11D±0.20) with 58 eyes within ±0.50 D and 60 eyes with ± 1.00D of target correction . For achieved cylinder 60 eyes (100%) had ≤0.50D and 51 eyes (85%) had ≤0.25D with strong positive linear correlation between achieved and expected cylinder(r=0.94)

Conclusions:

The results of the present study support safety,efficacy, predictability of toric implantable collamer lens implantation to treat moderate to high myopic astigmatism.
