| Summary: | AIM: To evaluate the relation between the position shift of intraocular lenses(IOL)and the change of refraction, after phacoemulcification with IOL implantation.<p>METHODS: This study analyzed the anterior chamber depth, the change of the refraction, the distant vision and the near vision in 102 eyes of 102 patients at 1, 3, 6mo and 2a after phacoemulcification and monofocal one-piece foldable IOL implantation. The position shift of IOL detected by anterior segment optical coherence tomography(AS-OCT)was observed too. All of the patients were followed up for 24±3.8mo.<p>RESULTS: The distant vision of the 102 eyes after cataract surgery and IOL implantation at 1, 3, 6mo and 2a were 0.78±0.13,0.75±0.14,0.72±0.12,0.72±0.10 respectively. The near vision were 0.38±0.12,0.41±0.13,0.46±0.12,0.47±0.10. The anterior chamber depth after surgerces were 3.75±0.16, 3.69±0.13, 3.61±0.12, 3.62±0.11mm. And the refractive degree was -0.47±0.26,-0.65±0.28,-0.93±0.24,-0.95±0.20. The position of the IOL was forward in the AS-OCT with time. The differences of the four indicators at 1, 3 and 6mo postoperatively were significant by multiple comparison(<i>P</i><0.05),while the difference was not significant between those at 6mo and 2a.<p>CONCLUSION: The movement of IOL in eyes after cataract surgery leads to the reduction of the distance vision and the increase of the near vision, which were stabilized at 6mo after surgeries. |
