Abstract
Objective: To evaluate the binocular vision function, validity and safety of implanted multifocal intraocular lens eye. Method: ultrasonic emulsified combined ReSTOR multifocal intraocular lens implantation surgeries were conducted for 25 eyes of 21 patients, including 17 patients with monocular surgeries and 8 patients with binocular surgeries. Then, patients’ post-operation distant and near visions, far and near visual functions and stereoscopic visual function were observed; the off-glasses rate, poor vision and satisfaction [1] were invested through questionnaires. The post-operation follow-up lasted for 3 to 18 months. Result: the distant and near visions of naked eyes of patients implanted with ReSTOR intraocular lens are respectively 0.84±0.20 and 0.62±0.27 for 3 months after surgeries; all patients have good near and far stereoscopic visual functions; the satisfaction about moderate-distance vision is 84.6% (21/25); the satisfaction about near vision is 93%; the near-vision off-glasses rate is 88% (25/22). Conclusion: multifocal intraocular lens can provide good distant and near visions, far, near and stereoscopic visual functions for patients; the patients implanted such lens in both their eyes can recover the stereoscopic visual function and their vision satisfaction is higher than that of patients implanted such lens in one of their eyes.
Highlights
1.1 Material A whole cluster of 21 patients with cataract and 25 eyes from January 2013 and December 2014 in the hospital were selected; the ages of patients were between 25 and 75 years old
In order to reduce errors in experimental results caused by human factors during operations, all operations were conducted by one doctor
Compound tropicamide was used for sufficient mydriasis; Benoxil eye drops were used in the eyes with operation at intervals for three times in total; the eye drops were used once every ten minutes
Summary
1.1 Material A whole cluster of 21 patients with cataract and 25 eyes from January 2013 and December 2014 in the hospital were selected; the ages of patients were between 25 and 75 years old (average age: 58±14). Inclusion criteria: the patients’ best corrected visual acuity is within 4.7; corneal astigmatism1.5D; pre-operation vision: index0.4; nuclear hardness: Class Ċ-Č. Patients with other lesions in their eyes should be excluded. Preoperative examination: vision, corrected visual acuity (CVA), intraocular pressure, A ultrasound, B ultrasound, corneal endothelial cell counting, corneal curvature, corneal topography, IOL-master, OCT, ocular anterior segment photographing, and lacrimal passage irrigation [2]. Materials and devices: Infiniti Vision system ultrasonic emulsifying machine and AcrysofReSTOR SN6A0D1 multifocal intraocular lens. All patients included had no severe physical illness so there’s no contraindication in surgeries
