AIM:To evaluate the postoperative intraocular lens(IOL)rotational stability and residual refractive astigmatism following combined 25-gauge vitrectomy and cataract surgery with implantation of a plate haptic toric ***:In this retrospective case series,32 eyes of 32 patients underwent a combined 25-gauge vitrectomy and phacoemulsification for vitreoretinal diseases and cataract with regular corneal astigmatism of at least 1 diopter(D).A plate haptic toric IOL(AT Torbi 709M,Carl Zeiss Meditec AG)was implanted in all *** outcome measures were rotational stability and refractive astigmatism up to 6mo postoperatively as well as the best corrected visual acuity(BCVA).RESULTS:Preoperative refractive astigmatism was 2.14±1.17 D,which was significantly reduced to 0.77±0.37 D six to eight weeks postoperatively and remained stable throughout the observation period(0.67±0.44 D at three months and 0.75±0.25 D at six months;for all groups:P<0.0001 compared to baseline).BCVA improved significantly from 0.36±0.33 logMAR preoperatively to 0.10±0.15 logMAR following surgery(P=0.02).Mean IOL axis deviation from the target axis was 3.4°±2.9°after six to eight weeks and significantly decreased over time(2.4°±2.6°six months after surgery;P=0.04).In one patient IOL,re-alignment was ***:Corneal astigmatism is significantly reduced following combined 25-gauge vitrectomy and cataract *** plate haptic toric IOL position and axis remain stable during the observation period of six months.

AIM：To evaluate the rotational stability and visual outcomes of a single-piece hydrophilic acrylic toric intraocular lenses（IOL） over a 1.5-year follow-up *** from the 6-month follow-up study have been previously ***：Forty eyes of 26 cataract patients（mean age：72.8±7.9y） with pre-existing corneal astigmatism of 1.0 to 2.6 D were enrolled in the *** axial length was 23.17±0.88 *** outcome measures after implantation of the Torica-a A IOL（Human Optics） were IOL rotational stability,subjective refraction,astigmatism correction,uncorrected and corrected distance visual acuity（UDVA,CDVA）.RESULTS：There was no significant change in the parameters evaluated between the 6-month and 1.5-year *** last visit,mean absolute IOL rotation（objective method） was 1.81°±1.87°（range 0.00° to 7.20°） with 78.6% of eyes having IOL rotation 〈3°,92.9% of eyes 〈5° and 100% of eyes 〈8°.No patient required secondary IOL repositioning during the course of the *** residual refractive cylinder was-0.60±0.40 *** was a significant reduction in the magnitude of the J0 vector postoperatively（P〈0.0001） with a mean absolute change of 0.76±0.40 *** mean J45 vector was close to zero preoperatively and postoperatively and didn＇t change significantly（P=0.28）.Mean monocular UDVA and CDVA was 0.09±0.12 log MAR and-0.01±0.12 log MAR,*** treatment with Nd：YAG laser was ***：The Torica-a A IOL shows good and stable visual performance and rotational stability over a 1.5-year follow-up period.

Journal of Clinical and Nursing Research 2024年第3期8卷 207-214页

作者： Jie Luo Yang Liu Bing Wang Lei Li Junyu Yang The Daqing Oilfields General Hospital Daqing 163001Heilongjiang ProvinceChina

Objective:To analyze the enduring rotational steadiness of AcrySof IQ Toric intraocular lens(IOL)in cataract patients suffering from myopia in a long-term ***:A retrospective study was conducted on a case series involving 78 patients.A total of 120 eyes with an axial length(AL)ranging from 24-30 mm and corneal astigmatism≥1.50 D underwent implantation of AcrySof IQ Toric IOL guided by the version navigation *** eyes were divided into two groups based on *** A included 60 eyes with high myopia(AL≥26 mm),while Group B consisted of eyes with low to moderate myopia(24 mm≤AL0.05).The percentage of rotation degrees under 5°was recorded as 98.22%.After the procedure,the BCDVA was 0.1322±0.03 *** was a substantial increase in theχvalue after the operation as compared to the pre-operativeχ^(2) value(χ^(2)=76.79).The standard deviation of preoperative corneal astigmatism was statistically significant(P<0.05)at 2.17±1.08 *** the surgical procedure,the remaining astigmatism was measured at 0.41±0.26 *** data showed a notable gap in statistical significance(t=4.281,P<0.05).Conclusion:The AcrySof Toric IOL was a reliable solution for managing corneal astigmatism in cataract patients with my
