[Abstract]:Objective to explore the effectiveness, safety, predictability and stability of compensated laser cutting with presbyopic spherical aberration.
Methods From 2005 to 2008, 24 presbyopic patients (21 myopic patients, 3 hyperopic patients, 13 laser in situ keratomileusis (LASIK) and 23 laser subepithelial keratomileusis (LASIK) were included in the study. In the experimental group, 12 patients were all female, mean 47.09 years old, mean spherical equivalent (SE) was - 2.98DS. In the control group, 12 patients (5 males, 7 females, mean 48.33 years old, mean preoperative SE was - 5.20DS) were matched with preoperative age, SE, ADD value and operation time. The refractive index of the dominant eye was -0.25DS and the refractive index of the non-dominant eye was - 0.50DS. The refractive index of the dominant eye was - 0.25DS and the refractive index of the non-dominant eye was - 1.OODS in the control group. Corrected distant visual acuity (CDVA), uncorrected distant visual acuity (UDVA), uncorrected near visual acuity (UNVA), hyperopia corrected near visual acuity, binocular simultaneous visual acuity, contrast sensitivity (CS). WFA-1000 aberration meter measured the whole eye aberration and observed the spherical aberration. (spherical aberration, SA) (Z (4,0)) early and long-term changes after surgery. Pentacam measured corneal anterior surface curvature, calculated the mean of K value at radius 2 mm and 4 mm (K2mm, K4m), observed the continuous changes of K2 (corneal vertex K-K2mm), and K 4 (K2mm-K4m). The mean follow-up time was 4.5 years. SPSS13.0 statistical software. Statistical analysis of data showed that P0.05 was statistically significant.
Results UNVA was 0.20 at 3 months and 0.40 at 4.5 years after surgery, which was 2 rows lower than that at 3 months (p = 0.019). There was no significant difference in near vision (p = 0.365) between non-dominant eyes and dominant eyes (p = 0.041) after 4.5 years (p = 0.298). 4.5 years after operation, the mean value of UDVA LogMAR in both eyes of the experimental group was - 0.03 and that of the control group was 0.01. The mean value of UNVA LogMAR in both eyes of the experimental group was 0.38 and 0.30 respectively. There was no difference between the experimental group and the control group in UDVA and UNVA (p = 0.096, P = 0.054). There was no significant difference in postoperative CDVA between the experimental group and the control group (p = 1.000). There was no significant difference in spatial frequency CS between the experimental group and the control group (n = 9) at 6 months after surgery and at 4.5 years after surgery, compared with the preoperative spatial frequency of 1.6 and 0.7 visual angles. The CS value of glare was slightly increased (p = 0.025, P = 0.046; n = 12), and the CS value of glare was slightly increased (p = 0.042, n = 11) at the spatial frequency of 1.0 degrees. The average expected SE value of non-dominant eyes in the experimental group was - 0.50DS, 4.5 years after operation was - 0.53DS, which was not different from the expected SE value (p = 0.268). The ADD value of the experimental group was not different before and after operation, but that of the control group was higher than that before operation (p = 0.012). ADD in the experimental group was smaller than that in the control group (p = 0.041). The mean SA in the non-dominant eye was - 0.045 micron at 6 months after operation and - 0.190 micron before operation, and the difference was statistically significant (p = 0.022, n = 8); the mean SA in the non-dominant eye was - 0.143 micron at 4.5 years after operation, which was not significantly different from that before operation (p = 0.359, n = 11), and was positively different from that of the dominant eye (p = 0.002, n = 11). The mean value of preoperative K2 was - 0.022D in the experimental group and 0.303D in the postoperative 4.5 years. The difference was statistically significant (p = 0.005, n = 9). The mean value of preoperative K4 was 0.066D, and 0.362D in the postoperative 4.5 years. The difference was statistically significant (p = 0.010, n = 9). The delta K decreases and the K4 changes greatly.
Conclusion Old parallax compensated laser ablation is effective, safe and predictive in the short term. Its long-term effectiveness and stability need to be further explored by enlarging the sample.
