Abstract:
This restrospective case included 40 patients(79eyes)who underwent implantable collamer lens or toric implantable collamer lens implacement. Uncorrected and corrected distance visual acuities, refractions, posterior chamber intraocular lens vault,intraocular pressure,endothelial cell loss,cylinder axis of the toric intraocular lens were evaluated for moderate to high myopia and astigmatism. 2 years or above after operation mean uncorrected and corrected distance visual acuities were 0.830±0.269 and 0.980±0.241 respectively. The mean spherical equiva-lent was ( -0.66±1.08) D postoperatively. 29 eyes had implanted toric intraocular lens, which 24 eyes were un-der 15 degrees of the intended axis, 1 eye was under 30 degrees of the intended axis and 4 eyes were above 30 de-grees of the intended axis. The mean intraocular pressure was(1.76±0.41)kPa. The endothelial cell density loss was 11.18%. The mean vaults at 6 months and 2 years or above were (0.510±0.141)mm and (0.442±0.117) mm respectively. A statistically significant difference was found ( P <0.05 ) . Two sets of data were in the normal range. Phakic posterior chamber intraocular lens implantation appears safe and effective,which provides long-term predictable,stable refractive results.
