“…However, if the opacity is small or located in the peripheral part of the crystalline lens, it is deemed visually insignificant. 3,4 The visual system in children is underdeveloped, and if a visually significant cataract is not treated, it can lead to amblyopia. The surgical approach for pediatric cataract is distinct from that of adults, with a focus on addressing posterior capsular opacification and preventing amblyopia.…”

Objective: To compare intraoperative complications in manual posterior capsulorhexis (forcepsorhexis) and posterior vitrectorhexis, before implantation of the IOL in patients of paediatric cataract surgery. Study Design: Observational study. Setting: Department of Ophthalmology, Shaheed Mohtarma Banazir Bhutto Medical University Larkana. Period: July 2021 to June 2022. Methods: Our study included patients within the age range of 1-12 years who were diagnosed with congenital cataract and did not exhibit any other abnormalities in the anterior or posterior segments. A comprehensive ophthalmic and systemic examination was conducted, and the patients were categorized into two groups: Group A for Forceps Capsulorhexis and Group B for Posterior Vitrectorhexis. Results: There were a total of 154 cases of paediatric cataracts that underwent surgical procedures known as Posterior capsulorhexis (forcepsorhexis) and posterior vitrectorhexis. Both groups had participants with ages ranging from 1 year to 12 years, with a minimum age of 1 year. The mean age for the Forceps Capsulorhexis group was 6.1+1.8 years, while the mean age for the Posterior Vitrectorhexis group was 6.9+1.3 years. The outcomes during surgery showed that in the Forceps Capsulorhexis group, 60 patients (77.92%) had organization of the capsular bag, while in the Posterior Vitrectorhexis group, 49 patients (63.63%) had organization of the capsular bag. Additionally, 55 patients (71.42%) in the Forceps Capsulorhexis group experienced vitreous thrust into the anterior chamber, compared to 66 patients (85.71%) in the Posterior Vitrectorhexis group. Conclusion: The safety and effectiveness of Forceps capsulorhexis as a treatment for paediatric cataract surpasses that of the posterior vitrectorhexis procedure, as concluded by our study.

“…These neuropeptides allow for cell differentiation and specialization. When there is loss of nerve function, homeostasis cannot be maintained and this can lead to inflammation, tissue damage, and poor wound healing [2 ▪ ,3 ▪ ]. These factors must be taken into account when considering patients for refractive surgery…”

Purpose of reviewCorneal nerve function is an important consideration for the refractive surgeon. In patients without a history of neuropathy, refractive surgery can lead to destruction of corneal nerves and may predispose to keratopathy. The purpose of this review is to provide an update on the effect of refractive surgery on corneal nerve function and the potential for an increased risk of neurotrophic keratopathy development. Recent findingsRecent studies have reinforced that refractive surgery can cause anatomical and functional changes in corneal nerve function. Among the most commonly performed refractive surgery procedures are Laser Assisted In-situ Keratomileusis, Photorefractive Keratectomy, and Small Incision Lenticule Extraction. Due to differences in technique, these procedures can have varying effects on corneal nerve structure. Using in vivo confocal microscopy, postrefractive patients were found to have decreased total nerve density when compared with controls in the immediate postoperative period. In some studies, patients have been shown to undergo re-innervation and regain significant amounts of nerve function. The majority of studies have found that despite decreased nerve cell density, long-term outcomes of refractive surgery patients are generally favorable. However, loss of corneal nerve function can lead to a variety of serious effects ranging from dry eye disease, corneal hypoesthesia/anesthesia, neuropathic pain, to neurotrophic keratopathy and ulceration in the rare cases. SummaryNeurotrophic keratopathy is a rare occurrence after keratorefractive surgery and is largely due to damage to corneal nerves. Proper patient selection and counseling are essential to decrease the risk of development of this devastating complication.
