Purpose:
To study of the target refraction to improve the visual quality in patients implanted with ReSTOR® SN6AD1 IOL(intraocular lense)
Setting:
: Department of Ophthalmology,
Seoul St. Mary's Hospital,
College of Medicine, The Catholic university of Korea
Methods:
This study included 128 patients (160 eyes) that had undergone cataract surgery and after 6 postoperative months, had their visual acuity at far score higher than 0.8. Then these patients were divided into 4 groups. The patients’ uncorrected visual acuity(UCVA) at far distance and near were better than 0.8 and better than J1 in the first group (Group 1), better than 0.8 and worse than J1 in the 2nd group (Group 2), worse than 0.8 and better than J1 in the 3rd group (Group 3) and worse than 0.8 and worse than J1 in the last group (Group 4). And we compared the postoperative refractive errors of the four groups
Results:
At 6 months postoperatively, the spherical equivalent(SE) was -0.12±0.51 in group 1, 0.08±0.54 in group 2, -0.60±0.60 in group 3 and 0.02±0.73 in group 4. There were statistical differences in SE of group 3 compared to others. The group 1 and 3 who had better visual acuity at near distance show the negative value of SE, and the group 3 and 4 who had worse visual acuity at far distance show the larger portion of the absolute value of SE more than 0.5 than group 1 and 2
Conclusions:
When we plan the refractive power in multifocal IOL insertion, it is different from monofocal IOL insertion. And as the SE moves to more myopic shift, the visual acuity is better at near distance and as the absolute value of SE is more than 0.5, the visual acuity at far distance can be worse
