Morphological analysis of lacrimal punctum using anterior segment optical coherence tomography in different age groups.

Purpose: To evaluate the lacrimal punctal changes in different age groups using anterior segment optical coherence tomography (AS-OCT).

Methods: A cross-sectional observational study was conducted between January 2023 and January 2024 including healthy subjects between 20 and 80 years. The selected eyes from healthy patients were divided into four age groups (21-35 years, 36-50 years, 51-65 years, 66-80 years), and lower lacrimal puncta were analyzed using AS-OCT.

Comparison between opposite clear corneal incision versus toric intraocular lens in correcting astigmatism.

Purpose: To compare the visual outcomes and efficacy of opposite clear corneal incision (OCCI) and toric intraocular lens (IOL) implantation in correcting preexisting astigmatism (PEA) in patients undergoing phacoemulsification.

Methods: This prospective interventional comparative study was conducted between June 2022 and January 2023 in patients having cataract with PEA undergoing phacoemulsification. Patients were divided into two groups - group A underwent phacoemulsification with OCCI and group B underwent phacoemulsification with toric IOL implantation.

Comparison of visual outcomes in patients implanted with Tecnis Eyhance ICB00 and 1-Piece ZCB00 monofocal intraocular lenses.

Purpose: To compare the visual outcomes and monocular defocus curve of a new monofocal Tecnis Eyhance IOL (Tecnis ICB00) with Tecnis 1 single piece (ZCB00).

Methods: Eighty patients diagnosed with cataract were divided into two groups: Tecnis ICB00 (n = 40) and ZCB00 (n = 40). The visual outcome was evaluated using the following parameters: uncorrected distance visual acuity (UDVA), uncorrected intermediate visual acuity (UIVA), uncorrected near visual acuity (UNVA), corrected distance visual acuity (CDVA), distance corrected intermediate visual acuity (DCIVA), corrected near visual acuity (CNVA), uncorrected visual acuity contrast sensitivity (UVACS), best-corrected visual acuity contrast sensitivity (BCVACS), manifest refraction, and defocus curve and was compared at the 6th week and 3 months after surgery.

Conjunctiva in strabismus surgery - to stitch or to stick? - A randomized clinical trial.

Purpose: To evaluate the clinical outcomes with fibrin glue in comparison with vicryl sutures for limbal conjunctival wound closure in strabismus surgery.

Methods: In this prospective interventional study, patients undergoing horizontal muscle strabismus surgery were randomized into two groups: the vicryl suture group and the fibrin glue group. The limbal conjunctival incisions were closed with 8-0 vicryl in the suture group and with fibrin glue in the other group.

Outcomes of refractive implantable lens implantation after deep anterior lamellar keratoplasty.

Purpose: To assess the refractive outcomes and effect on endothelial cell density of refractive implantable lens (RIL) implantation following deep anterior lamellar keratoplasty (DALK).

Methods: A retrospective study was conducted on 10 eyes of 10 patients who had undergone DALK and subsequently underwent toric RIL implantation. The patients were followed up over a period of 1 year.

Comparison of different endophthalmitis prophylactic measures in cataract surgery - An analysis of 2.4 lakh cases.

Purpose: To compare different endophthalmitis prophylaxis methods adopted in cataract surgery (manual small-incision cataract surgery and phacoemulsification) between the years 2013 and 2021 in the community eye care section of a tertiary eye care hospital in South India and report their outcomes.

Methods: All cataract surgeries performed from January 2013 to December 2021 (2,46,874 surgeries) at a single center were included in this retrospective study. The different endophthalmitis rates with each regimen were analyzed and evaluated.

T cell-inducing vaccine durably prevents mucosal SHIV infection even with lower neutralizing antibody titers.

Recent efforts toward an HIV vaccine focus on inducing broadly neutralizing antibodies, but eliciting both neutralizing antibodies (nAbs) and cellular responses may be superior. Here, we immunized macaques with an HIV envelope trimer, either alone to induce nAbs, or together with a heterologous viral vector regimen to elicit nAbs and cellular immunity, including CD8 tissue-resident memory T cells. After ten vaginal challenges with autologous virus, protection was observed in both vaccine groups at 53.

Performance of a New-Generation Extended Depth of Focus Intraocular Lens-A Prospective Comparative Study.

Purpose: The aim was to study the visual performance of a new refractive extended depth of focus (EDOF) intraocular lens (IOL).

Design: Prospective, comparative study.

Methods: Consenting patients with age-related cataract willing for bilateral cataract surgery within 2 weeks were implanted with the Supraphob EDOF IOL and those willing for 1 eye surgery were implanted with a monofocal IOL.

Safety & efficacy of single subconjunctival triamcinolone 5 mg depot topical loteprednol post cataract surgery: less drop cataract surgery.

Aim: To do a randomized prospective interventional study for comparing the effects of a single subconjunctival triamcinolone acetonide (SCTA) injection to tapering topical loteprednol in patients undergoing phacoemulsification surgery under topical anesthesia.

Methods: A total of 400 patients were randomized into 2 groups; Group A (200 patients) received 5 mg SCTA at the end of surgery and topical ketorolac tromethamine (0.5%) with ofloxacin (0.

A virtual model to assess maximum treatable area in LASIK and feasibility of a temporal hinge.

Purpose: To generate virtual models using different hinge locations and to investigate the advantages of a temporal hinge to a superior in LASIK.

Methods: The study design was cross sectional. An image processing software was used to construct virtual LASIK models of 56 slit lamp photos of eyes.

Blepharitis: always remember demodex.

Purpose: To determine the incidence and density of Demodex species on the eyelashes of subjects with normal eyelids, anterior blepharitis (AB), meibomian-gland dysfunction (MGD), and mixed blepharitis (MB).

Materials And Methods: One hundred and fifty consecutive patients diagnosed with AB, MGD, and MB were recruited. An additional 50 individuals were recruited who were free of lid and margin disease to serve as a control group.

Relation of pulse pressure and arterial stiffness to concentric left ventricular hypertrophy in young men (from the Bogalusa Heart Study).

Differences in geometric adaptation of the left ventricle and associated cardiovascular risk may reflect the differential effects of classic risk factors and arterial stiffness on the left ventricle. In the present study, the influence of cardiovascular risk factors and arterial stiffness indexes on left ventricular (LV) geometry types were studied in a large community-based cohort of young adults. As part of the Bogalusa Heart Study, echocardiographic examinations of the heart were performed on 786 black and white adults (age range 24 to 43 years, average 36; 42% men, 70% white).
