“…The surgical principles and techniques are as follows: During the process of phacoemulsification, it is important to reduce stress on the zonules and posterior capsule, which are very fragile after vitrectomy 14. In addition, small pupils may have a negative effect on the operation in some cases, requiring the surgeon to minimize damage to the intraocular tissue 15. The key to surgical technique is that the nucleus was transferred out of the capsular bag and the phacoemulsification was performed in the anterior chamber.…”

Objective:To evaluate the characteristics, safety and effectiveness of a modified technique of phacoemulsification in post-vitrectomy cataracts.Methods:This retrospective clinical trial comprised 31 patients (31 eyes) with post-vitrectomy cataract, who had undergone phacoemulsification combined with intraocular lens implantation. An alternative surgical technique known as phacoemulsification in the anterior chamber was used for nucleus management in those cases. The following parameters were evaluated: best corrected visual acuity (BCVA), ocular inflammation, intraocular pressure, endothelial cell count and surgical complications.Results:Three months after surgery, the BCVA improved significantly compared with that before surgery (Z=-10.547; p<0.05). There were no significant differences in IOP before and after surgery (Z=-0.474; p>0.05). There was a statistically significant postoperative decrease in endothelial cell densities (Z=-3.916; p<0.05). The mean endothelial cell loss was -8.71%. A little inflammatory response in the anterior chamber in 11 eyes and mild corneal edema in 8 eyes were observed on the first day after surgery, which subsided after a week. The posterior capsular opacification were observed in three eyes, two of which were denser, and the YAG laser was performed for posterior capsular incision. No obvious surgical complications occurred.Conclusion:The modified technique of phacoemulsification, with phacoemulsification in the anterior chamber, is safe and effective to deal with post-vitrectomy cataracts.

“…34 Posterior capsular rupture rates were also reported to be less common in eyes operated on by residents (0% vs 3.0%) 36 and (0% vs 3.1%) 37 or in operations on vitrectomized eyes (0% vs 12%). 38 These figures of less than 1% should be considered as PCR is associated with an increased risk of endophthalmitis (OR 6.33, 95%, CI 4.22∼9.49) as well as an increased risk of retinal detachment. 39 Secondary surgery to suture a lens into the sulcus is less than optimal for a multifocal or extended depth of focus lenses and may lead to an unhappy patient, especially one expecting a precise refractive outcome.…”

Femtosecond laser-assisted cataract surgery (FLACS) was introduced with the hope of making cataract surgery safer and making the refractive result more predictable. It is only in the last four years that level 1 prospective randomised controlled trials (RCT) using current technology have been published. These, along with a meta-analysis of recent studies have shown that there seems to be little long-term visual benefit when using FLACS with monofocal lenses. The promised decrease in ultrasound energy required to remove a cataract has not been consistently demonstrated. There is level one evidence that the rate of posterior capsular rupture is less with FLACS using modern software. The round capsulotomy may be of increasing importance with the uptake of toric, multifocal and extended depth of focus lenses where a predictable capsulotomy size and precise placement of the lens becomes more important.

“…3,45 This may lead some to consider femtosecond laserassisted cataract surgery (FLACS). In the case series of 24 eyes by Wang and colleagues, 46,47 it was noted that all capsulorrhexis were completed without tags or tears, though there was no discussion regarding the choice of FLACS specifically to manage anterior capsular rigidity. If the patient has previously had a gas or silicone oil tamponade, or if there are any posterior capsular defects, then FLACS will need to be performed with an increased posterior safety margin to protect the posterior capsule.…”
