摘要:
目的:研究两种功能型多焦点人工晶体对白内障患者人工晶体植入术后视觉质量及晶体偏心、倾斜度的差异。方法:采用前瞻性研究,选取 2023 年 1 月—2023 年 12 月收治的 95 例拟行白内障超声乳化吸除联合人工晶体植入术的患者作为研究样本,通过随机数字表法分为区域折射型组(42 例)及衍射型组(53 例)。因人工晶体光学设计差异,无法对手术医师实施术式盲法;术后视力检测者、量表评估者及数据统计分析者采用单盲法。区域折射型组植入区域折射多焦点人工晶体,衍射型组植入衍射型多焦点人工晶体。比较两组患者手术前后裸眼远、中、近视力及离焦曲线,采用屈光分析测量仪检测术后不同时间点人工晶状体偏心量、倾斜度,通过中文版 VF-14 视功能指数量表评价视觉质量,采用白内障视功能相关生存质量简表(Catquest9SF-CN)评估生活质量。结果:两组术后裸眼远、中、近视力均较术前显著改善(均P<0.05);衍射型组术后中视力、近视力优于区域折射型组(Z=2.815、2.602,均P<0.05),两组术后远视力差异无统计学意义(P>0.05)。离焦曲线显示,衍射型组在 + 0.00 D 和 - 3.00 D 处的裸眼视力优于区域折射型组。重复测量方差分析结果显示,区域折射型组术后 1 周、1 个月、3 个月的人工晶体偏心量[分别为(0.40±0.12) mm、(0.43±0.13) mm、(0.45±0.11) mm]和倾斜度[分别为 (0.41±0.10)°、(0.42±0.13)°、(0.45±0.16)°]均低于衍射型组[同期偏心量:(0.50±0.14) mm、(0.61±0.12) mm、(0.70±0.17) mm;同期倾斜度:(0.57±0.11)°、(0.65±0.14)°、(0.73±0.17)°],偏心量和倾斜度在时间上均发生显著变化,且两组间存在显著差异,同时组别与时间存在显著交互作用(时间效应F=12.352~15.678,均P<0.001;组间效应F=38.914~42.185,均P<0.001;交互效应F=8.743~9.216,均P<0.01)。衍射型组术后 3 个月 VF-14 量表评分为(53.31±5.19)分,高于区域折射型组(42.40±3.89)分(P<0.05)。两组治疗后 Catquest9SF-CN 量表评分[区域折射型组(12.49±2.10) 分,衍射型组(11.93±2.50) 分]差异无统计学意义(P>0.05)。结论:两种功能型多焦点人工晶体均可有效改善白内障患者术后视觉质量,其中衍射型多焦点人工晶体在中、近视力及主观视觉功能评分上更具优势,区域折射型多焦点人工晶体在术后晶体偏心控制和倾斜度稳定性方面表现更优。
Abstract:
Objective: To study the differences in visual quality,lens eccentricity and inclination in cataract patients after intraocular lens implantation caused by two functional multifocal intraocular lenses, namely regional refraction type and diffraction type. Methods: A prospective study was conducted. A total of 95 patients who were scheduled to undergo phacoemulsification aspiration combined with intraocular lens implantation for cataract from January 2023 to December 2023 were selected as the research samples. They were divided into regional refraction type group(n=42) and diffraction type group (n=53) by the random number table method. Due to the differences in the optical design of intraocular lenses, surgical blinding couldn′t be implemented for surgeons. However, single-blind methods were adopted for postoperative visual acuity tests, scale evaluations, and data statistical analyses. The regional refraction type group was implanted with regional refraction multifocal intraocular lenses, while the diffraction type group was implanted with diffraction multifocal intraocular lenses. The uncorrected distant, medium and near visual acuity and defocus curves of the two groups of patients before and after the operation were compared. The eccentricity and inclination of the intraocular lens at different time points after the operation were detected by the refractive analysis measuring instrument. The visual quality was evaluated by the Chinese version of the VF-14 visual function Index scale. The quality of life was evaluated using the Short Form of Cataract Visual Function Related Quality of Life (Catquest9SF-CN). Results: The uncorrected distant, medium and near visual acuity of both groups after the operation was significantly improved compared with those before the operation (all P<0.05). The median visual acuity (0.12±0.07) and near visual acuity(0.09±0.07) in the diffraction group after surgery were better than those in the regional refraction group (Z=2.815, 2.602, both P<0.05), while there was no statistically significant difference in distant visual acuity between the two groups after surgery (P>0.05). The defocus curve showed that the uncorrected visual acuity of the diffraction group at + 0.00D and -3.00 D was better than that of the regional refraction group. The results of repeated measures analysis of variance showed that the eccentricity of the intraocular lens [(0.40±0.12) mm, (0.43±0.13) mm, (0.45±0.11) mm, respectively] and the inclination [(0.41±0.10)°, (0.42±0.13)°, and (0.45±0.16)°,respectively] at 1 week, 1 month, and 3 months after the operation in the regional refraction type group were all lower than those of the diffraction type group [simultaneous eccentricity: (0.50±0.14) mm, (0.61±0.12) mm, (0.70±0.17) mm; concurrent inclination degrees: (0.57±0.11)°, (0.65±0.14)°, (0.73±0.17)°]. Both decentration and tilt changed significantly over time, and significant differences were observed between the two groups. Furthermore, a significant interaction between group and time was found (time effect F=12.352-15.678, all P<0.001; inter-group effect F=38.914-42.185, all P<0.001; the interaction effect F=8.743-9.216, all P<0.01). The score of the VF-14 scale in the diffraction group was (53.31±5.19) points 3 months after the operation, which was higher than that in the regional refraction group (42.40±3.89) points (P<0.05). There was no statistically significant difference in the Catquest9SF-CN scale scores between the two groups after treatment [(12.49±2.10) points for the regional refraction type group and (11.93±2.50) points for the diffraction type group] (P>0.05). Conclusion: Both types of functional multifocal intraocular lenses can effectively improve the postoperative visual quality of cataract patients. Among them, the diffractive multifocal intraocular lens has more advantages in medium and near vision and subjective visual function scores, while the regional refractive multifocal intraocular lens performs better in postoperative lens eccentricity control and tilt stability.
