Ever-evolving modern day cataract extraction techniques have been accompanied by the use of smaller quantities and less invasive methods of anesthesia. Topical anesthesia is routinely used for phacoemulsification. However, peribulbar block or some modification of it is used for anesthesia in manual small-incision cataract surgery (MSICS) by most practitioners. The authors describe a technique using a combination of 1.5-2 milliliters of anesthetic mixture given subconjunctivally and supplemented with commercially available intracameral anesthetic and mydriatic for MSICS. It is possible to get high level of anesthetic effect and ease of surgery with this technique though there is a small learning curve. Several modifications from topical phacoemulsification like two side ports six o'clock hours apart make this surgery easy to adapt to. No special instrumentation is required. It gives adequate analgesia and anesthesia to complete the surgery. a minimalistic anesthetic approach in MSICS can be used with enhanced safety and by avoiding usual complications of traditional peribulbar and retrobulbar anesthesia.

Objective The objective of this study is to compare patient-reported outcome measures using the Catquest Questionnaire in patients undergoing phacoemulsification (Phaco) versus manual small-incision cataract surgery (MSICS). Materials and methods This descriptive cross-sectional study included patients aged 40 years and older with cataracts classified as nuclear sclerosis (NS) grade 3 or higher. Demographic details were recorded and a comprehensive ophthalmological exam was done.

The aim of this article has been, on the one hand, to describe the use of MSICS (manual small incision cataract surgery) for the management of cataracts, especially mature ones, in relation to its particular utility in the field of humanitarian campaigns, for which a description of the MSICS technique has been made, subsequently a review of the available scientific literature has been carried out to verify the results of this technique in comparison with phacoemulsification and extracapsular surgery and to describe the importance of teaching this technique to all cataract surgeons, especially the ones participating in humanitarian campaigns. According to what has been found, MSICS is an excellent surgical technique and according to current evidence it seems to be the choice over phacoemulsification and/or the classic extracapsular technique in hyper mature cataracts, especially in the field of humanitarian campaigns, due to its lower rate of complications and the improvement in visual acuity obtained. According to the studies found, it would be possible for the experienced ophthalmologic surgeon to implement this technique since the learning curve is short.

Purpose: To compare corneal endothelial loss in manual small incision cataract surgery (MSICS) following three different techniques of nucleus delivery (Viscoexpression, Irrigating Vectis, Phacosandwich).
Setting: Mahatma Gandhi Medical College and Research Institute, Puducherry, India.
Design: Prospective, single blinded, randomized controlled trial.
Purpose: To evaluate the visual outcomes of keratorefractive lenticule extraction using a new version of a femtosecond laser platform with semi-automated cyclotorsion compensation in comparison to the previous generation without cyclotorsion control.
Methods: This was an ambispective study of consecutive eyes treated by SMILE with the VisuMax and VISUMAX 800 femtosecond lasers at the Uma Eye clinic, Chennai, India between June 2022 and July 2023. Inclusion criteria were myopia up to -10 D and astigmatism between 1.

Background/objectives: Ebola virus disease (EVD) survivors develop post-acute ophthalmic sequelae, including a high prevalence of uveitis that may be complicated by vision-threatening cataract. After the non-detection of Ebola virus (EBOV) RNA in sampled ocular fluid, vision impairment due to cataract can be treated safely and effectively via manual small incision cataract surgery (MSICS). However, the long-term ocular visual outcomes and assessment of ocular tissues, including for genomic RNA, have been infrequently or not reported in Western African survivors.
