有晶状体眼后房型人工晶状体植入术矫正高度近视

目前,屈光性手术方法众多,主要可分为两大类:一类是角膜屈光性手术,另一类是晶状体屈光性手术.前者包括角膜镜片术或表面角膜移植术、角膜磨镶术、角膜内镜片植入术(如角膜基质内角膜环植入术)、放射状角膜切开术(RK)、自动板层角膜成形术(ALK)、准分子激光角膜切削术(PRK)以及准分子激光原位角膜磨镶术(LASIK)等.后者如透明晶状体摘出术包括植入与不植入后房型人工晶状体、有晶状体眼植入双凹或凹凸前房型人工晶状体、有晶状体眼植入后房型人工晶状体等.以往的各种屈光性手术均存在诸多的缺点和并发症,相对而言,有晶状体眼后房型人工晶状体植入术,除具备有晶状体眼前房型人工晶状体植入术的诸多优点外,人工晶状体植入更符合生理解剖状态,并大大减少了并发症,被视作一种前景甚好的屈光性手术.

Choroidal neovascularization in phakic eyes with anterior chamber intraocular lenses to correct high myopia

PURPOSE: To analyze the appearance, incidence, and characteristics of choroidal neovascularization (CNV) in patients with high myopia corrected by implantation of a phakic anterior chamber intraocular lens (PACL). SETTING: University Miguel Hernández, Instituto Oftalmológico de Alicante, Alicante, Spain. METHODS: The CNV observed in 294 consecutive eyes (181 patients) implanted with a PACL for the correction of high myopia (-7.0 to -38.0 diopters) was studied. The mean follow-up was 50.6 months +/- 32.8 (SD) (range 6 to 120 months). RESULTS: Choroidal neovascularization occurred in 5 eyes (1.70%); 3 eyes were in women, and 2 were in men. The interval between PACL implantation and CNV was 63.2 +/- 27.3 months (range 18 to 87 months). The CNV was subfoveal in 4 eyes and juxtafoveal in 1 case. The mean best spectacle-corrected visual acuity (BSCVA) after PACL implantation and before the appearance of CNV was 0.53 +/- 0.18 (range 0.4 [20/50] to 0.8 [20/25]); after CNV appeared, it was 0.26 +/- 0.18 (range 0.05 [20/400] to 0.5 [20/40]), a statistically significant difference (P =.001, paired Student t test). In 2 cases, the CNV was treated with photodynamic therapy (PDT); in the other 3 cases, PDT was rejected. The cumulative risk for CNV (Kaplan-Meier survival analysis) in highly myopic patients corrected by PACL implantation was 0.43% at 18 months and 5.4% at 87 months. CONCLUSIONS: Implantation of a PACL to correct high myopia was followed by a small incidence of CNV (cumulative risk of 5.4% at 87 months). The appearance of CNV was followed by a significant decrease in BSCVA.

Abstract：

Objective To definitute axial length measuring mode of the phakic eyes after posterior chamber implantation of lens. Methods All patients came from the Ophthalmology Hospital of China Medical University . Seventy patients with 135eyes,aged 21-48 years old. Among this group 28 were male,53eyes;42 were female, 82 eyes. A-ultrasound and IOL-Master was used to measure axial length one week before preoperative and three months after ICL implantation. There are two measuring mode in A-ultrasound and IOL-Master: normal and special. All the results were analysed by the SPSS11.5 statistical methods.Results (1) preoperative AXL of A-ultrasound and IOL-Master average are: (27.81 ±0.22) mm,(28. 02 ±0.22) mm; (2) postoperative AXL of phakic and Pseudophakic PMMA mode of IOL-Master average are: (28.01 ±0. 22) mm, (28. 12 ±0.22)mm; (3) postoperative AXL of normal and special mode of A-ultrasound average are: (27. 82 ± 0. 22 ) mm, ( 26. 40 ± 0. 21 ) mm. Conclusion According to the different meansuring mode, there are some difference of AXL between the preoperative and postoperative ICL.The more accurately meansuring mode is IOL-Master phakic mode before and after operation. A-ultrasound normal mode can be used if the lens become so turbid that the AXL can't be obtained by IOL-Master.     

Five-year follow-up after anterior iris-fixated intraocular lens implantation in phakic eyes to correct high myopia

Purpose

To evaluate the 5-year follow-up of safety, efficacy, predictability, stability, and complications of anterior iris-fixated phakic intraocular lens (pIOL) implantation to correct high myopia, and patients'' satisfaction after implantation.

Design

Prospective, nonrandomized, and comparative (self-controlled) trial.

Methods

A prospective clinical trial of 84 eyes of 43 patients with high myopia was conducted. Uncorrected visual acuity (UCVA), best spectacle-corrected visual acuity (BSCVA), refraction, endothelial cell count, intraocular pressure (IOP), anterior chamber depth, slit lamp biomicroscopy, and indirect ophthalmoscope were measured preoperatively and postoperatively.

Results

At the 5-year follow-up, UCVA was significantly improved, with 85.7% of eyes reaching 20/25 or better. No eyes experienced a loss in BSCVA, and 71.4% gained one or more lines of their preoperative BSCVA. There was a significant reduction in spherical errors in all patients after operation. Loss of endothelial cells was observed 3 years after operation and no more loss was observed 4 years after operation in statistical analysis. No increase in IOP was observed 5 years after operation in statistical analysis. No intraoperative complications were observed in this study. However, pigment precipitates of varying intensities on the lens optic were noted in all patients 1 day after operation, and only five eyes were observed to have the pigment residual five years after operation.

Conclusion

At the 5-year follow-up, the implantation of the anterior iris-fixated pIOL was proved to be effective, predictable and capable of reversibility to correct high myopia in phakic eyes. It was a safety addition to the laser refractive surgery. However, longer follow-up with larger numbers of patients is still necessary to evaluate long-term complications.

Medennium posterior chamber phakic refractive lens to correct high myopia

PURPOSE: To determine the efficacy and safety of phakic refractive lens implantation to correct high myopia. METHODS: In this prospective study, a phakic refractive lens was implanted in 90 myopic eyes in which refractive errors ranged from -6.00 to -20.00 diopters (D) and laser refractive surgery was contraindicated. Uncorrected visual acuity (UCVA) and best-spectacle corrected visual acuity (BSCVA), manifest and cycloplegic refractions, and intraocular pressure (IOP) were assessed during a 1-year follow-up period. Possible complications, including endothelial cell counts, were evaluated. RESULTS: Spherical equivalent refraction measurements revealed a significant change from the preoperative mean value of -11.90+/-5.00 D to 0.04+/-0.20 D 1 year postoperatively (P=.001). The UCVA and BSCVA significantly improved postoperatively (P=.001 and P=.01, respectively). Seventy-two (80%) eyes and 61 (68%) eyes were within +/-1.00 D and +/-0.50 D of the target refraction, respectively. A significant increase in IOP was found at every postoperative visit (P=.01). There was a trend toward decreased endothelial cell density postoperatively, although the difference did not reach significance. No major complications were found during the 1-year follow-up period. CONCLUSIONS: The implantation of a phakic refractive lens seems to be a predictable and well-tolerated procedure for correcting high myopia. Complications such as development of cataract, implant dislocation, decreases in endothelial cell counts, or development of glaucoma did not occur in this study.

目的：我们应用眼前节全景分析仪(Pentacam)测量有晶状体眼后房型人工晶状体(ICL)植入术手术前后前节形态指标,评价有晶状体眼后房型人工晶状体植入术的安全性及稳定性。

方法：选取行有晶状体眼后房型人工晶状体植入术治疗的高度近视患者48例90眼,术后随访6mo。Pentacam眼前节全景分析仪测量各时间点的中央前房深度(ACD)、3：00位前房角(ICA)、角膜像差(CA)、角膜曲率(K)和角膜厚度(CCT)等指标。使用SPSS 19.0统计软件,描述术前术后各指标的分布特征,采用配对t检验对各指标进行手术前后的差异性比较。

结果：所有观察指标各时间点均呈正态分布。ACD、3：00位ICA较术前降低(P<0.05)。CA中,总像差(CTA)及低阶像差(CLOA)较术前无统计差异(P>0.05),高阶像差(CHOA)则较术前有所增加(P<0.05); K略有减小(P<0.05)。CCT较术前比较均无统计学差异(P>0.05)。对于术后有统计学意义变化的指标,均在术后1mo时即达到稳定状态。

结论：应用眼前节全景分析仪(Pentacam)观察有晶状体眼后房型人工晶状体植入术眼前节形态的变化主要有ICA变窄,ACD变小,CHOA增加,K减小,尚在安全范围内,6mo随访中各值均保持稳定,未出现并发症,但远期效果需进一步随访观察。
