Abstract:AIM:To observe the visual quality of super-high myopia after implantation of the visian implantable collamer lens with centra-flow(ICL V4c)in the short-term.
METHODS: The clinical date of 78 patients(100 eyes)were collected, the preoperative uncorrected visual acuity(UCVA)was below 0.10, spherical refraction was -13.25±2.05(-11.25~-20.00)D. The preoperative and postoperative refrative condition, wavefront aberration, visual acuity and contrast sensitivity were examined.
RESULTS: The postoperative UCVA in 97 eyes(97%)were equal to or more than 0.7. Thirty-seven eyes(37%)were equal to or more than 1.0. Both the contrast sensitivity and glare contrast sensitivity under high spatial frequency were increased at postoperative 1mo, there were statistical differences(all P<0.05). Both the higher-order aberrations, coma, spherical, second coma and second spherical were increased at postoperative 1mo, there were statistical differences(P<0.05). At postoperative 1mo, 2 eyes' original lens had cloudy, 2 eyes' intraocular pressure had increased, 3 eyes had corneal reaction, 1 eye had glare and halos. At postoperative 6mo, all visual symptoms almost disappeared.
CONCLUSION: The visual quality of super-high myopia after implantation of ICL V4c was improved obviously in short-term.
