Financial disclosure: J.P.D received assistance with travel expenses from Lenstec (Barbados) Inc. Spectacle independence has become increasingly important in the current ageing population. Cataractous or clear lens extraction with multifocal intraocular lens (MF-IOL) implants offers a unique opportunity for ametropic presbyopes to regain spectacle independence. Purpose: Study aim: To evaluate the 1 year post-operative visual outcomes with a rotationally asymmetric multifocal IOL design. The SBL-3 (Lenstec (Barbados) Inc.), is a dual optic, bi-aspheric acrylic MF-IOL with a +3.0 dioptre (D) near add. Available in 0.25 D increments. 财政披露 :J.P.D 接受了 Lenstec (Barbados) Inc. 的差旅费用支持 现如今, 脱镜已变得越来越重要 植入 SBL-3 多焦晶体替换白内障及清晰的晶体为老视患者脱镜提供一个独 特的机会 目的 : 研究目的 : 评估非旋转对称多焦晶体 SBL-3 植入术后 1 年的视觉效果 SBL-3(Lenstec (Barbados) Inc.) 是双 区域的双非球面丙烯酸酯多焦晶体, 近附加度数为 +3.0D 部分度数范围以 0.25D 递增 Setting: site for eyes, Refractive Surgery Unit, Sunderland Eye Infirmary, UK. Methods: Prospective study of 40 consecutive patients (80 eyes) having presbyopic refractive lens exchange surgery (single surgeon) with bilateral SBL-3 implantation. Inclusion criteria included no pre-existing ocular pathology and less than 1 D of corneal astigmatism.
Patients were recalled for review 1 year following surgery. Pre- and post-operative data collection included manifest refraction, monocular and binocular unaided and corrected vision, both distance and near. Complications were recorded. Patient satisfaction was also assessed. 定位 :site for eyes, Refractive Surgery Unit, Sunderland Eye Infirmary, UK. 方法 : 40 位患者 (80 只眼 ) 通过老视屈光晶体替换手术双眼植入 SBL-3 的前瞻性研究 包含标准 : 无眼部疾病病史及角膜散光 <1D 术前及术后数据收集包括显然验光 单眼及双眼裸眼视力和矫正视力 ( 包括远视力及近视力 ), 记录相 关并发症及评估患者满意度 Results( 结果 ): 95% of eyes were within 1.0 D and 78% within 0.5 D of target refraction. Participants: Forty patients (80 eyes), mean age 61 years (range 47-76 years) enrolled. Pre-operative manifest refraction spherical equivalent (MRSE) was +1.72 2.15 D (range -6.50 to +6.13 D). No surgical complications. Thirty patients (75%) had attended for 1 year review. Post-operative MRSE was -0.05 0.39 D. (range -1.13 to +1.00 D) 1 eye required secondary corneal LRI s for residual astigmatism. 21 eyes (35%) had undergone YAG laser capsulotomy. 23% of patients had some mesopic dyphotopic symptoms but only 10% found this had an effect on night time driving. 95% 的患眼在目标屈光度数的 ±1.0D 以内,78% 在 ±0.5D 内 参与者 :40 位患者 (80 只眼 ), 平均年龄 61 岁 (47-76 岁之间 ) 术前 MRSE 为 +1.72 2.15 D( 范围在 -6.50 to +6.13 D 之间 ); 无手术并发症 ; 30 位患者 (75%) 已随访 1 年 ; 术后 MRSE 为 -0.05 0.39 D( 范围 -1.13 to +1.00 D; 1 只眼因为残余散光需要二次角膜 LRI; 21 只眼 (35%) 已行 YAG 激光囊膜切开术 ;
23% 的患者存在暗室下异常光适应症状, 但发现只有 10% 在夜间驾车有影响 ; Results: Monocular unaided vision Unaided distance vision (UDVA): 结果 : 单眼裸眼视力 裸眼远视力 (UDVA): Monocular UDVA: 20/40 or better in 97% of eyes 20/20 or better in 63% of eyes 单眼 UDVA: 97% 患眼视力在 20/40 及以上 ; 63% 患眼视力在 20/20 及以上 ; Unaided near vision (UNVA)( 裸眼近视力 ): Monocular UNVA: N5 or better in 83% of eyes Monocular near VA with far correction: N5 or better in 83% of eyes
单眼 UNVA: 83% 患眼视力 N5 及以上 ; 远视矫正下的单眼近视力 83% 患眼视力 N5 及以上 ; Results: Binocular unaided vision Unaided distance vision (UDVA): 结果 : 双眼裸眼视力 裸眼远视力 (UDVA): Binocular UDVA: 20/32 or better in 100% of eyes 20/20 or better in 87% of eyes 双眼 UDVA: 100% 患眼的视力为 20/32 及以上 ; 87% 患眼的视力为 20/20 及以上 Unaided near vision (UNVA)( 裸眼近视力 ):
Binocular UNVA: N5 or better in 93% of eyes Binocular near VA with far correction: N5 or better in 90% of eyes 双眼 UNVA: 93% 患者的视力为 N5 及以上 ; 远视矫正状态下的双眼近视力 : 90% 患者的视力为 N5 及以上 CONCLUSIONS: 93% of patients were satisfied with their unaided visual outcome for distance and near vision. Low incidence of significant or troublesome dysphotopsia s The 1 year visual and refractive outcomes are encouraging with a very high level of patient satisfaction. The SBL-3 (Lenstec Barbados Inc.) holds promise as an effective way to improve both unaided distance and near vision in patients undergoing presbyopic refractive lens exchange surgery. 结论 : 93% 的患者对裸眼远 近视力满意 ; 重大 / 令人烦恼的异常闪光感发生率低 ; 术后一年视觉及屈光效果获得了很高的患者满意度,SBL-3 (Lenstec Barbados Inc.) 承诺经过老视屈光晶体置换术后提高裸眼远视力及近视力
