Toric Posterior Chamber Phakic Iol For Correction Of High Myopia With Moderate Astigmatism - 5 Years Results

To present 5 year results for ICL toric posterior chamber phakic lens for correction of high myopia with moderate astigmatism.

LaserFocus – Centre for Eye Microsurgery, Belgrade, Serbia

One hundred and forty four eyes of eighty three young patients (45 males and 38 females) with mean age of 31 +/- 7 years (23 to 48) were enrolled in this prospective interventional case series. Preoperatively mean CDVA was 0.65 +/- 0.27 (0.30 to 1.00) with mean preoperative myopia of -8.97 +/- 3.79 (-1.25 to -18.00) D, refractive astigmatism of -2.32 +/- 1.11 (-1.00 to -4.00) D and topographic astigmatism of -1.98 +/- 1.12 (-0.50 to -3.75) D. All patients have been implanted a toric EVO + Visian ICL phakic lens (with centraFlow) by STAAR Surgical. 

All surgeries were uneventful. Three eyes showed excess vault of more than 1000 microns and the lenses were replaced by a smaller one of the same refractive power. Mean UDVA at 1 month achieved preoperative BDVA, while at 5 years safety index was 1.21, and efficacy index was 1.08. None of the eyes lost any lines of CDVA, 98 maintained, 38 gained one line, while 8 eyes gained two or more lines of CDVA. Myopia was reduced to -0.19 +/- 0.81 (+0.50 to -2.00) D, refractive astigmatism to -0.31 +/- 0.33 (0 to -0.75) D, while topographic astigmatism slightly increased -2.11 +/- 1.53 (-0.25 to -3.75) D (p>0.05). Vault at 5 years was 431 +/- 239 (94 to 720) microns.

Toric EVO + Visian ICL posterior chamber PIOL showed good predictability, safety and efficacy for correcting high myopia with moderate astigmatism.
