: To assess the impact of cataract surgery on intraocular pressure.: A study comprising of 60 patients from the district of Kolar, who underwent Manual small incision cataract surgery were examined with Goldmann applanation tonometer for assessment of intraocular pressure before surgery and 1 week, 1 month after surgery along with visual acuity assessment, anterior segment evaluation with slit lamp biomicroscopy, posterior segment evaluation using indirect ophthalmoscopy. 60 participants were included in the study, of whom 27 (45%) were female and 33 (55%)were male. The mean age of the patient was 64.2 years, with the maximum number of patients being in the age group of 61-70 (51.7%). The mean of intraocular pressure in pre-operative patients was 15.18 mmHg, after manual small incision cataract surgery at 1 week, it showed 11.96 mmHg and after 1 month showed 12.75 mmHg. The intra ocular pressure decreases significantly after manual small incision cataract surgery more so in female patients than male patients.

“…Manual small-incision cataract surgery (MSICS) is economical, secure, and has favourable optical outcome. 4 One of the major determinant of refractive status of the eye is cornea. 5 However, new developments in surgery has also led to a variety of new corneal complications, such as endothelial damage, epithelial toxicity, DM detachment, sterile corneal ulcer, etc.…”

: To assess corneal complications and visual outcome of manual small incision cataract surgery.: This study comprises of 227 patients in a tertiary care centre in Kolar district, who underwent MSICS were examined for corneal complications and visual outcome postoperatively on Day 1, 1 week, and at the end of 6 week also visual acuity (VA) assessment, anterior segment evaluation with slit lamp biomicroscopy, posterior segment evaluation using indirect ophthalmoscopy, and keratometry was done.227 participants were included in the study, of whom 138 (61%) were female and 89 (39%) were male. The maximum number of patients being in the age group of 61-70 (42.7%). OCTET grading was done for corneal edema patients and on post op Day 1, total 62 patients who had corneal edema in the study were graded according to OCTET classification, and 6 patients (9.6%) had grade 1, 17 patients (27.4%) had grade 2 and 39 patients (63%) had grade 3. At the end of 6 week postoperatively, 45 patients had clear cornea, and 5 patients (8%) had grade 1, 6 patients (9.5%) had grade 2, and 7 patients (11.1%) had grade 3, and 82.3% of patients had VA of 6/6 to 6/9 followed by 11% had 6/12 to 6/18 and 6.6% had 6/24 to 6/36.: Small incision cataract surgery is most cost-effective surgery if corneal endothelium is protected during surgery and will have early visual rehabilitation.

BACKGROUND: Phacoemulsification, being the safest technique, is the golden standard of cataract surgery worldwide. However, as any surgery, it is accompanied by inevitable damage to intraocular structures. The most prevalent among them is the loss of corneal endothelial cells. In order to prevent these complications, various viscoelastics with particular features and characteristics are widely used. AIM: To compare the anatomical and functional state of ocular structures after standard phacoemulsification with monofocal posterior chamber intraocular lens (IOL) implantation using domestic (Kogevisc and Adgevisc) and foreign (Viscoat and Amvisc Plus) viscoelastics. MATERIALS AND METHODS: 60 cataract patients (60 eyes) were included in the clinical study, which were divided into two equal groups. In the first group (30 patients, 30 eyes), Adgevisc and Kogevisc (Solofarm, Russia) were used during the procedure. The mean age of the patients was 66 11 years. In the second group (30 patients, 30 eyes), Viscoat (Alcon) and Amvisc Plus (BauschLomb) were used. The mean age of the patients was 69.03 10.44 years. All patients underwent phacoemulsification with the implantation of the AcrySof IOL (model SA60AT, Alcon) according to the standard technique. Visual acuity, IOP level, CCT, corneal endothelial cell density were assessed. All studies were performed before surgery, the next day, 7 days and 1 month after surgery. RESULTS: In patients of the second group, on the 1st (p 0.05) and 7th day (p 0.01) after surgery, a statistically significant increase in IOP was revealed compared to the first group. The central cornea thickness in the early postoperative period was higher in patients of the second group, however, it was not statistically significant. The loss of corneal endothelial cells 1 month after surgery was 8.5 7.0% (p 0.01) in the first group and 6.6 6.4% in the second group (p 0.01). The mean value of endothelial cell loss in patients of the first group was higher, however, it was not statistically significant. The best corrected visual acuity in both groups at all stages of follow-up after surgery (days 1, 7 and 30) was comparable, there was no significant difference between the groups. CONCLUSIONS: The clinical efficacy of domestic adhesive and cohesive viscoelastics Adgevisc and Kogevisc (Solofarm, Russia) in phacoemulsification using the soft-shell technique is comparable to the foreign analogues Viscoat (Alcon) and Amvisc Plus (Bausch Lomb), which is confirmed by the absence of statistically significant differences in the studied parameters of the postoperative state of ocular structures and explained by their similar composition, molecular weight and viscosity.
