Impact of posterior vitreous detachment on contrast sensitivity in patients with multifocal intraocular lens

Eye diseases such as myopia, hyperopia, astigmatism, and cataract are have affected most people at home and abroad for many years. With the development of science and technology, people who wear glasses are now younger, and they are on the rise over time. This paper is to explore the visual function after the implantation of continuous visual range human cocrystal micromonocular vision in both eyes of the patient. On this basis, the latest visual sensor technology is used to conduct clinical research on the operation, a case-control study is performed on the patient’s eyes, followed by intraocular lens insertion surgery, one eye is hemitrope and the other eye has a certain degree of intraocular lens inserted, and it is recorded within a period of time after the operation. According to the analysis of the experimental results, the patient’s naked eye and corrected distance vision is (t = 2.102, P = 0.049), middle distance vision (t = 1.403, P = 0.200), and near vision (t = 1.463, P = 0.216). After the operation, the ratio of patients taking off glasses 91.8%. After the continuous visual range intraocular lens micromonocular vision design, it can well correct the patient’s near and far vision of the naked eye of both eyes.

“…In line with these findings, we previously reported a reduction in contrast sensitivity in eyes with epiphora caused by lacrimal passage obstruction, in which conventional visual acuity is maintained [ 1 ]. A contrast sensitivity test is also useful for evaluating the quality of vision before and after treatment in various anterior segment disease of the eyes, such as dry eye [ 25 , 26 ], ptosis and dermatochalasis [ 27 ], conjunctivochalasis [ 28 ], and cataract [ 29 ], as well as posterior segment eye diseases such as retinal detachment [ 30 ], epiretinal membrane [ 31 ], and posterior vitreous detachment [ 32 ], among others [ 33 ]. To the best of our knowledge, this is the first study to report improvement in the contrast sensitivity of the eyes after LPI for epiphora owing to lacrimal passage obstruction.…”

This prospective case series aimed to investigate the contrast sensitivity function before and after lacrimal passage intubation (LPI) in eyes with epiphora due to lacrimal passage obstruction. We included 58 eyes of 51 patients who underwent LPI for lacrimal passage obstruction. The best-corrected visual acuity (BCVA), contrast sensitivity function, and lower tear meniscus were compared before LPI and one month after lacrimal duct stent removal. The area under the log contrast sensitivity function (AULCSF) was calculated for the analyses. Lower tear meniscus was assessed using anterior segment optical coherence tomography. The BCVA was comparable (p = 0.61) before and after LPI, while AULCSF increased significantly after treatment (before LPI: 1.29 ± 0.17, after LPI: 1.37 ± 0.14, p < 0.0001). Treatment resulted in a significant increase in contrast sensitivity at all spatial frequencies, 3–18 cycles/degree (p < 0.01 for 3, p < 0.01 for 6, p < 0.0005 for 12, p < 0.05 for 18 cycles/degree). The lower tear meniscus parameters improved significantly after treatment (p < 0.005); however, no correlation between the changes in the tear meniscus and those of the AULCSF was found. The contrast sensitivity significantly improved after LPI in eyes with epiphora due to lacrimal passage obstruction.
