Effect of cortical cleaving hydrodissection on posterior capsule opacification in age-related nuclear cataract

Abstract

Although no difference was noted in the incidence of PCO, in eyes that had PCO, the percentage of the area of the central posterior capsule involved by PCO was significantly lower in eyes that had multiquadrant cortical cleaving hydrodissection than in those that did not.

Effect of hydrodissection alone and hydrodissection combined with rotation on lens epithelial cells

“…The results favored the hydrodissection group at 4 years. 8 In the present study, cell loss in the hydrodissection group supports our previous results ( Figure 2, A to C). The difference in the hydrodissection alone and the hydrodissection combined with rotation groups reflects that we did not only nudge the nucleus to confirm the separation of the cataract from the capsule.…”

“…5 The beneficial effects of LEC removal on posterior capsule opacification (PCO), were seen in our study of adult subjects. 8 Hydrodissection is followed by rotation, and rotation confirms the total separation of the cataract from the capsular bag. We believe that hydrodissection followed by rotation of the nucleus within the capsular bag effectively scrapes the LECs off the capsule, especially those lying deep in the fornices of the capsular bag in the preequatorial region.…”

“…Our clinical evaluation of adults supports their observation because the incidence of PCO in eyes subjected to hydrodissection was significantly lower at the 4-year follow-up. 8 We believe that hydrodissection combined with rotation of the nucleus causes friction between the cataract and LECs, which could scrape the LECs off the capsule. We designed this experimental study of human cadaver eyes to test the belief that LECs are scraped off the capsule after hydrodissection combined with rotation, especially in the PZ and EZ.…”

Impact of anterior capsule polishing on anterior capsule opacification after cataract surgery: a randomized clinical trial

“…Mechanical removal of the LECs is achieved using hydrodissection with rotation and cortical clean-up after phacoemulsification. 24, 25 Mathey et al 26 studied five techniques of polishing the lens capsules. They observed that the cleanest capsule was obtained by using an ultrasound irrigation/aspiration tip.…”

Translational medicine: transforming research into clinical practice

“…An example in which basic and clinical research was blended is cited here. The effect of cortical cleaving hydrodissection on posterior capsule opacification (PCO) in age-related nuclear cataract was tested in a clinical scenario [3]. It was observed that in eyes that exhibited PCO, the percentage of the area of the central posterior capsule affected by PCO was significantly lower in eyes that had multiquadrant cortical cleaving hydrodissection than in those that did not.…”
