| Summary: | AIM:To observe the effect of posterior chamber phakic intraocular lens implantation for high myopia on the stereopsis. To evaluate the implantation of implantable contact lens from the highest form of visual angle. <p>METHODS:Fourty-six patients(92 eyes)with high myopia were included from January to December 2014. The average age of patients was 26.13±3.37(19～32)years, and 20 males(43%)and 26 females(57%)were observed. Analysis the stereopsis of these patients before and after the implantation of posterior chamber phakic intraocular lens. <p>RESULTS:The mean spherical equivalent of all the eyes was 10.02±2.71D before and -0.02±0.25D after surgeries. There was significant difference on the spherical equivalent(<i>t</i>=14.062, <i>P</i>=0.000).There were 6 patients with the blind of near stereopsis, the near stereopsis of the rest patients were 637.50±462.08arcsec before the surgeries and there were none with the blind of near stereopsis after surgeries. The near stereopsis of all the patients were 126.09±165.78arcsec after surgeries. There were 12 patients with the blind of far stereopsis, the far stereopsis of the rest patients were 400.59±257.00arcsec before the surgeries. After surgeries there were 2 patients with the blind of far stereopsis, the far stereopsis of the rest patients were 152.73±111.65arcsec. There were both significant differences on the near stereopsis(<i>Z</i>=-5.725, <i>P</i>=0.000)and the far stereopsis(<i>Z</i>=-4.976,<i>P</i>=0.000)before and after surgeries.<p>CONCLUSION:Posterior chamber phakic intraocular lens implantation not only correct the ametropic of the high myopia, but also improve the visual acuity and the stereopsis. |
