AIM:To compare the efficacy of selective laser trabeculoplasty(SLT) in replacing medical therapy in pseudophakic and phakic eyes.METHODS:Subgroup of a prospective randomized clinical trial including patients with primary open angle glaucoma or ocular hypertension controlled with medication.Of 38 pseudophakic eyes were matched with 38 phakic eyes.SLT was offered as a way to decrease medication while maintaining the same low eye pressure.SLT was performed over 360°,at 3ns,spotsize 400 μm,100 spots.Data [intraocular pressure(IOP),number of medications needed] were measured at 1h,1wk,1,3,6 and 12 mo.An independent-samples t-test was performed to compare baseline characteristics of the phakic and the pseudophakic group and differences in evolution of mean IOP and number of used medications.Chi-squared analysis was performed to investigate proportions of fast,slow and non-responders.RESULTS:The mean IOP measurement was 13.00± 2.88 mm Hg in the phakic group(38 eyes) and 13.51±3.06 mm Hg in the pseudophakic group(38 eyes)(P〉0.05).This changed little after SLT and IOP lowering effect was comparable between the two groups.Main aim however was to lower the amount of medication needed.In the phakic group medication lowered from 1.29±0.62 at baseline,to 0.15±0.46 after 12mo;a reduction of 88.37%.In the pseudophakic group,used medication changed from 1.71±1.04,to 0.41±0.61;a 76.02% reduction.The differences were not statistically significant at any time point(P〉0.05).IOP lowering occurred slightly faster in thepseudophakic group(50% of patients after one week) than in the phakic group(68% of patients after more than 4wk).The difference was not significant(P〉0.05).CONCLUSION:IOP lowering effect of SLT is comparable between phakic and pseudophakic eyes. 展开更多

Objective:To explore the corrective effect of posterior chamber intraocular lens implantation with phakic eyes in the treatment of high myopia and astigmatism.Methods:From May 2023,the hospital began to collect the case data of diagnosis and treatment of high myopia and astigmatism.By May 2024,310 cases were included,all of which were treated with posterior chamber intraocular lens implantation.The visual acuity,astigmatism and axial position of the intraocular lens were observed before and after treatment.Results:At different time points after the operation,the patient’s vision was significantly improved compared with that before the operation(P<0.05),and the vision level was equal to or greater than the best-corrected vision before the operation.At different time points after the operation,the average rotation of the intraocular lens was less than 5 degrees.Astigmatism was significantly lower than that before the operation(P<0.05).After the operation,the intraocular pressure increased in 11 cases,accounting for 3.55%,with no adverse complications such as lens turbidity,glare and obvious halo occurring.Conclusion:The posterior chamber intraocular lens implantation with phakic eyes has an ideal correction effect in the treatment of high myopia and astigmatism,which can effectively improve the vision level of patients and reduce the degree of astigmatism,and has high effectiveness and safety. 展开更多

AIM: To assess the safety, efficacy and predictability of the AcrySof phakic angle-supported intraocular lens (IOL) (Alcon Inc., U.S.A.) for correction of high-to-extremely high myopia in adults. METHODS: In this prospective study performed in Tianjin Medical University Eye Center & College of Optometry, Tianjin, China, 25 eyes of 13 patients were implanted with AcrySof phakic angle-supported IOLs and followed for 1 year postoperatively. Preoperative manifest refractive sphere was (-12.08 +/- 2.44) diopters (D) and cylinder was (-1.35 +/- 0.62)D. Visual acuity, predictability and stability of manifest refraction spherical equivalent (MRSE), adverse events, and endothelial cell density were analyzed during 1-year of follow-up. RESULTS: After 1 year of follow-up, no eyes lost 1 line (best spectacle-corrected visual acuity)BSCVA; an uncorrected visual acuity (UCVA) of 20/20 or better was achieved in 60% of eyes; 100% had an UCVA of 20/40 or better; a BSCVA of 20/30 or better was achieved by 100% of eyes; 84% had a BSCVA of 20/20 or better. The overall mean percentage change in endothelial cell density 1 year after surgery was (-0.27 +/- 3.60)%. Two eyes (8%) had increased intraocular pressure (IOP) on the day of surgery. No pupil ovalization, pupillary block, or retinal detachment events were observed. CONCLUSION: After 1 year of follow-up, the implantation of AcrySof phakic angle-supported IOL is proved to be safe, effective and predictable with minimal complications in patients with high-to-extremely high myopia. Due to the limitation of visiting time, long-term of clinical investigation is necessary to verify the safety and efficacy of this IOL. 展开更多
