Re-inventing the straight incision with a single central suture in manual small-incision cataract surgery to minimize surgically induced astigmatism.

Purpose: To calculate the surgically induced astigmatism (SIA) in MSICS through a superiorly placed straight scleral incision closed with a single, central, perpendicular 10-0 polyamide suture and to document any suture-related complaints and complications.

Methods: A retrospective, hospital-based study was carried out in 50 cases of uncomplicated senile cataract (>50 year) with nuclear sclerosis ≥ grade 4, "with the rule" astigmatism who underwent MSICS through a superior, straight incision with a single, central, perpendicular 10-0 nylon suture. Patients with "against the rule" astigmatism, keratoconus, pre-existing corneal opacity, astigmatism >2D, distorted or oblique mires, and previous ocular surgeries and unwilling to participate were excluded.

Comparison of surgically induced astigmatism in chevron, straight, and frown incisions in manual small-incision cataract surgery.

Purpose: : The study was conducted to calculate and compare the surgically induced astigmatism (SIA) in chevron, frown, and straight incisions in manual small-incision cataract surgery (MSICS).

Methods: A prospective, hospital-based study was conducted on 90 patients aged 50 years and above with nuclear sclerosis of grade 4 or more. Each group had 30 patients, divided into Group V (chevron incision), Group S (straight incision), and Group F (frown incision).

Association of near work and dim light with myopia among 1400 school children in a district in North India.

Purpose: The aim of this study was to determine the association of near work and dim light with myopia among school children in a district in North India.

Methods: This study included a total of 1400 children of either sex studying in classes 5-10 in various schools of a district in North India, after taking consent from their guardians. Visual acuity was measured using Snellen's chart.
