Phacoemulsification in posterior polar cataract

Abstract

Approved by the following research ethics committee: Selcuk University Faculty of Medicine (#2014/206). ABSTRACTPurpose: To evaluate the results and complications of phacoemulsification surgery in eyes with posterior polar cataracts and compare the techniques of vis codissection and hydrodissection. Methods: The medical records of 29 consecutive patients (16 males, 13 females) with posterior polar cataracts (44 eyes) who had undergone cataract surgery were retrospectively reviewed. Patients were divided into two groups according to the technique used; viscodissection was applied to the experimental group (group 1) and hydrodissection to the control group (group 2). Results: The postoperative best corrected visual acuity (BCVA) was 0.19 ± 0.22 logMAR (mean ± standard deviation) (range 0.00-0.70) in group 1 and 0.25 ± 0.18 logMAR (range 0.00-0.70) in group 2. Although the mean postoperative BCVA in group 1 was greater than that in group 2, the difference was not statistically significant (p=0.165). The mean postoperative BCVA was significantly greater than the mean preoperative BCVA in both groups (p=0.00). Intraoperatively, posterior capsular rupture occurred during the removal of the cortex in three eyes (13%) of group 1 patients, with vitreous loss and anterior vitrectomy in one eye only. In group 2, six eyes (28.5%) presented posterior capsular rupture, and anterior vitrectomy was performed because of vitreous loss in three eyes. Although the percentage of posterior capsular rupture was greater in group 2, the difference was not statistically significant (p=0.207). Conclusions: Complications in posterior polar cataract surgeries can be overcome by being careful throughout the surgery and using proper techniques. Viscodissection may be better for avoiding posterior capsular rupture than hydrodissection.

Comparison of the outcomes of phacoemulsification and manual small-incision cataract surgery in posterior polar cataract - A retrospective study

“…Chetinkaya et al . [ 20 ] compared the techniques of viscodissection and hydrodissection in PPC cases undergoing phacoemulsification and found that 13% of the cases had PCR with viscodissection and 28.5% had PCR with hydrodissection. Langwińska-Wośko et al .…”

Telephone follow-up of the elderly after cataract surgery

“…Researchers conducted a study in which they observed that the mean time to onset of symptoms of postoperative complications was 6 days (when assessed from 1 to 30 days) for cataract surgery (Coelho, Souza, & Tanure, 2015). Other authors stated that the estimated time for postoperative complications after cataract surgery is typically up to 3 days after the surgical procedure (Hayashi, Sasaki, Manabe, & Hirata, 2018; Luz, Cvintal, Silva, & Padoveze, 2018; Nizamani, Bhutto, & Talpur, 2013) and may occur until the 30th day after (Cetinkaya, Cetinkaya, Dadaci, & Acir, 2016; Mattos, Saraiva, Angotti-Neto, & Passos, 2013; Råen, Sandvik, & Drolsum, 2013; Toyama, Ueta, Yoshitani, Sakata, & Numaga, 2018). This fact corroborates this study, since, at the third evaluation performed on the 30th postoperative day, the DSR diagnosis decreased.…”

Pac-Man Method: A New Technique for Nuclear Management Of Posterior Polar Cataract

“…There is a great aspect of posterior capsular dehiscence ranging from 4% to 36% 2 and the association of amblyopia.. 3 Bilateral involvement is more common (65 to 80%) than unilateral one. 3,4 Various techniques have been introduced to ensure a safer surgery 5,6 in PPC cases, and Phacoemulsification is the preferred technique. If there is any ambiguity about pre-existing posterior capsule dehiscence, anterior segment optical coherence tpmpgraphy (OCT) or Scheimpflug imaging can be used to confirm and document it., 7 Every patient should be counselled about the possibilities of complications like posterior capsule tear (PCT) or lens drop, 2,3,8 and the surgeon must be ready for any mishap.…”
