Two-mm chord manual small-incision cataract surgery with phacofracture: A brief exposition of the surgical technique

We describe a surgical technique for manual small-incision cataract extraction with 2-mm chord incision with phacofracture. The authors describe a curvilinear 2-mm chord incision 1.5 mm behind the limbus and antiparallel to the limbus with back cuts of variable length; 1.5 mm for foldable lenses and 2.5�mm for the rigid nonfoldable lenses. Continuous curvilinear capsulorhexis with a 26-G bent needle cystitome (or Utrata forceps) is followed by cortical cleaving hydrodissection and cartwheeling of the nucleus into the anterior chamber. A specially designed Sahu modified vectis (SMV) and a flattened visco cannula are used for the phacofracture. The heminuclei are removed along their longitudinal axis and direct implantation of the pseudophakos. Surgically induced astigmatism was found to be a mean change in astigmatism of 0.14 DCyl when the axis was ignored. Corneal endothelial counts were not vastly different from the routine manual small-incision and phacoemulsification at 3 months of follow-up. The technique used here by the surgeon for cataracts of any C (1� or any P (1� to grade NC4 NO4 as graded by the LOCS III. Case selection is of paramount importance. Two-millimeter chord MSICS with phacofracture can deliver low astigmatism and good visual recovery in cataract surgery.

State of the nation survey on cataract surgery in India

Purpose: To study the knowledge, attitudes, and practices of the ophthalmologists in India regarding cataract extraction practices. Methods: A prospective, online, descriptive study was conducted from January 2022 to April 2022 using a self?developed validated questionnaire attached which was administered through a generated link. Results: The mean age of these 153 respondents was 47.02 (SD = 11.53) years with a male preponderance (70.59%). The majority (52.9%) had completed a fellowship after their post?graduation, and 56.20% provided sub?specialty services. Comprehensive ophthalmology (69.93%) and anterior segment (50.32%) practice were the most popular. Although 76.47% of respondents used a mix of techniques, 11.11% surgeons used only phaco?emulsification and 9.8% used only manual small? incision cataract surgery (MSICS) as the lone cataract treatment modality. Roughly 38% felt that outcomes were comparable for phaco?emulsification and MSICS, whereas about 44% opined that the outcomes of phaco?emulsification were better. MSICS outcomes were reported to be better by approximately 15%. The frown incision (53.59%), the straight incision (19.60%), and the straight incision with back cuts (10.45%) were popular. The majority (71.24%) of the respondents were willing to train fellow ophthalmologists and youngsters in MSICS. Standalone practices and family practices (42.48%), private eye institutes (10.45%), medical colleges (12.41%), and government non?teaching hospitals (11.11%) were the major service providers. 4% were working in rural hinterland. Conclusion: The majority of the surgeons use a mix of cataract extraction operative techniques. A large, willing talent pool of manual small?incision cataract surgeons exists. India can be a global hub for MSICS delivery and training

Early postoperative astigmatism in 2-mm manual small incision cataract surgery with phacofracture

Purpose: India’s cataract surgery rate has been hovering around a creditable 6000 per million population but the coverage is variable across the geography and demography with sharp urban rural divide. Smaller incisions in manual small incision cataract surgery (MSICS) with phacofracture have been credited with lower astigmatism and faster recovery, which is especially useful for patients traveling for surgeries. Methods: In this retrospective chart analysis based observational study of 66 eyes, we describe the early postoperative results with 2 mm MSICS with phacofracture. Results: The mean spherical equivalent of the autorefractor measured astigmatic error changed marginally to ?0.51 diopters (SD = 0.58) from ?0.44 diopters (SD = 0.42) (t = ?8.410, P = 0.0) translating to mean change in astigmatism of 0.14 DCyl when the axis was ignored. The keratometric difference between steepest and flattest axis of the anterior surface of the central 3 mm zone of the cornea changed from a mean of 0.89 diopters (SD = 0.55) to 1.39 diopters (SD = 1.03). The visual acuity improved to mean logarithm of the minimum angle of resolution (logMAR) score of 0.27 (SD = 0.33) at 1 week and 0.007 (SD = 0.04) which corresponds to 6/6P on Snellen’s acuity at 1 month or more. Conclusion: A 2 mm MSICS with phacofracture can deliver low astigmatism and good visual recovery in cataract surgery. The study underlines the need for considering the refraction at anterior and posterior corneal interfaces when the triplanar incision with separate interfaces is used.

Neuromyelitis optica spectrum disorder post-COVID-19 infection: A rare case report from Northeast India

Multiple sclerosis and neuromyelitis optica spectrum disorder may be seen in the acute setting of coronavirus disease 2019 (COVID-19) infection or even post-recovery. Such patients may present with optic neuropathy along with weakness in the back and lower limbs. Ascending paralysis can present with respiratory distress in acute COVID-19 infection and may even prove to be fatal. We report a unique case of a 16-year-old female with past history of COVID-19 infection having optic neuropathy, and radioimaging showing demyelinating plaques in the central nervous system with spinal cord edema. Serology showed positivity for rheumatoid arthritis, and the patient was managed with steroids and rituximab.

Transient myopia due to choroidal effusion: A novel ocular complication of COVID-19 infection

COVID-19 was declared as a global pandemic by the WHO in 2020. Although it is a respiratory virus, ocular complications and manifestations of the infection have been reported in different forms. We report a case of transient myopia and narrow angles due to choroidal effusion following infection by the SARS-COV-2 virus. We propose that the ability of the virus to incite an inflammatory response in the host body may be the mechanism behind the disease entity. This is a novel, previously undocumented ocular complication in case of a COVID-19 infection

Single stage surgery for Blepharophimosis syndrome.

Purpose: The purpose of this study was to report the functional and cosmetic outcome of single stage surgical procedure for correction of the classic components of Blepharophimosis syndrome. Materials and Methods: We report a retrospective case file review of 11 patients with Blepharophimosis syndrome operated between July 2004 and April 2008. Each patient had undergone the correction of epicanthus inversus, telecanthus, palpebral phimosis, and bilateral ptosis as a single-stage surgical procedure. Patients were examined and photographed before and after surgery. The mean follow-up was 3 years (range 2-6 years). Results: A total of 11 patients (8 males, 3 females) with a mean age of 9 years (range 6--22 years) were reviewed. The surgical outcome was assessed both functionally and cosmetically. The mean preoperative visual acuity was 0.729 ± 0.316 SD and the mean postoperative visual acuity was 0.856 ± 0.277 SD (P <0.0428). There was a statistically significant decrease of astigmatism following ptosis correction (P<0.05), improvement of telecanthus (P<0.0001) in terms of IICD (inner intercanthal distance), and HPFL (horizontal palpebral fissure length) (P=0.019) along with improvement of the superior visual field. The mean preoperative and postoperative IICD was 3±0.33 SD and 2.418 ± 0.189 SD, respectively. There was also a significant postoperative improvement of ptosis (P< 0.01), as measured by IPFH (vertical interpalpebral fissure height). All the patients had a stable functional and cosmetic result after a mean follow-up period of 3 years. Conclusion: Single-stage surgical correction of the classic anomalies of Blepharophimosis syndrome provides stable and successful long-term results.
