[Abstract]:objective
The visual acuity, the best corrected visual acuity, and the difference of contrast sensitivity and aberration were compared between the cataract phacoemulsification and the MCX11ASP aspheric intraocular lens and the AS spherical intraocular lens.
Method
1, a prospective clinical control study was carried out in a continuous selection of patients with age-related cataract in June 2011 - December 2011 in our hospital and performed routine cataract surgery (such as slit lamp microscope examination, fundus examination, A, B), corneal curvature, intraocular pressure, electrophysiology, etc., and preoperative removal of corneal lesions, glaucoma, and grapes Meningitis, subluxation of lens, retina disease, middle high myopia. Before operation, two groups of.A groups were implanted in the German human optical MCX11ASP aspheric intraocular lens, and the B group was implanted with AS spherical intraocular lens.
2, postoperative screening criteria: follow up patients after surgery, routine examination of Ophthalmology, corneal pathological changes without slit lamp microscope, no atrophy of the iris, no pigmentation, direct pupil and indirect reflection of light, the intraocular lens is located in the bag, in the middle, no obvious tilt, no apparent pigmentation, no cloudy surface of the artificial lens surface, no cloudy, no cloudy. The surface was damaged, the posterior capsule was cloudy, and there was no pathological change in vitreous and retina.
3, A, and B two groups were used to measure the visual acuity of the naked eye with the normal visual acuity, and the best corrected visual acuity. Three months after the operation, the Talcagi-CGT-1000 automatic glare contrast sensitivity test was used for the non glare and glare contrast sensitivity examination, the Nidek optometry was used to check the refractive state, and the aberration of the three months after the operation was examined by the OPD-Scan wavefront aberrometry.
4, the SPSS13.0 software package was used for statistical analysis, and T test and X2 test were used for the two groups of measurement results.
Result
1, all the subjects were examined one week after the operation. 3 patients (4 eyes) were out of visit one month after the operation, including 2 cases (3 eyes) in group A and 1 cases (1 eyes) in group B. 5 cases (7 eyes) were out of visit in 5 cases (7 eyes) and B group 3 cases (4 eyes) at three months after operation.
2, in group two, the average degree of intraocular lens implantation was 21.23 + 2.16 (D) in group A and 21.97 + 2.24 (D) in group B. There was no significant difference between the two groups (t=1.692, P = 0.0936). Among them, 6 patients (6 eyes) were slightly biased, partial center was less than 0.25mm, A group 2 (2 eyes), B group 4 cases (4 eyes). (-1.25D to 0.75D), group B -0.1258 + 0.6159D (-1.25D ~ 1.25D), the difference between the two groups was not statistically significant (t = 0, P=1.000). The degree of astigmatism in the A group was 0.5486 + 0.3526D (0 ~ 1.25D), and the group was 0.5333 + (1 to 1). The two groups had no statistical significance (0.2083, 0.8354 = 0.8354).
3, one week after the operation, the visual acuity of the two groups was 0.35 + 0.16 in group A, and in group B 0.31 + 0.18. There was no statistically significant difference between the two groups (t = 1.1715, P = 0.2440). The visual acuity was 0.58 + 0.18 in group A and 0.54 + 0.17 in group B (t=1.0918, P=0.2777). The best corrected visual acuity in group A in three months after operation was 0.91 + 0.12, group B was 0.88 + 0.11, and group two was not statistically significant (t=1.2502, P=0.2143). The pupil size A group 3.49 + 0.53 (mm), B group (mm) T=0.0895, P=0.9289.
4, in the three months after the operation, the two groups were measured in 6.3, 4, 2.5, 1.6, 1, and 0.7, respectively, under the condition of non glare and glare, and the two groups were significantly different in the 6.3 angle (P0.01), and the group A was better than the B group.
5, when the pupil was measured from 3 to 4mm three months after the operation, the spherical aberration of group A was 0.003 + 0.015 mu m, the difference was 0.004 + 0.01 u m, and the difference was 0.040 + 0.025 M. between two groups, and the difference was not statistically significant (t1=0.3554, P1=0.6961; t2=1.1254, P2=0.2165). The spherical aberration of the group m.B was 0.120 + 0.095 m, and the difference between the two groups was statistically significant (0.202, 0.129, M.) (t1=4.8398, P1=0.001:t2=2.0993, P2=0.0385).
conclusion
1, there was no significant difference in the visual acuity and best corrected visual acuity between three months after the operation of MCX11ASP aspheric intraocular lenses in Germany compared with AS spherical intraocular lenses.
2, the contrast sensitivity of MCX11ASP aspheric intraocular lens group is better than that of AS spherical intraocular lens group at 6.3 degree angle (low spatial frequency).
3, when the pupil diameter is 5.0mmm, MCX11ASP aspheric intraocular lens can significantly reduce the total aberration after cataract surgery and improve the visual quality of cataract patients after cataract surgery compared with AS spherical intraocular lens.
