Aim: To evaluate correction of pre-existing astigmatism after foldable Toric IOL implantation in patients undergoing cataract surgery.
Materal & Methods: In this prospective observational study we included 10 eyes of 10 patients with astigmatism between 2.00D to 6.00D &undergoing cataract surgery. Phacoemulsification was performed with Toric IOL implantation through 2.8mm clear corneal temporal incision. Patients were examined post operatively for Uncorrected Visual Acuity (UCVA), Best Corrected Visual Acuity (BCVA) & residual refractive astigmatism.
Statistical Analysis: Statistical analysis was performed by the SPSS program for Windows, ver.16.0.Continuous variables are expressed as mean ± SD, and categorical variables are presented as absolute numbers and percentage. For the statistical test, a p value less than 0.05 was taken to indicate a significant difference.
Results: The UCVA was 6/9 or better in 90% of eyes. 80% eyes achieved 6/6 BCVA. The mean refractive cylinder corrected from -3.4 ± 1.4 D to -0.60 ± 0.27 D which was statistically significant. (p value=0.0001).
Conclusion: Toric IOL implantation is an effective, safe surgical option to manage pre-existing corneal astigmatism during cataract surgery.

Aim: To compare different technique of nucleus delivery in small manual incision cataract surgery,regarding their safety and intra operative complication. Material & Methods: A total of 285 patients with cataract undergoing SICS with posterior chamber IOL implantation were selected. Patients were randomly divided into 7 groups of nucleus delivery. All of the patients were followed up on first postoperative day and discharge. Patients were advised regular follow up at 1st week, 4th week and 6th week. Results: Out of total 285 patients 68 (23.86%) patients had intraoprative complications for all the techniques. There was no intraoperative difficulty to the surgeon for delivery of nucleus by various techniques in 210(73.68%) of cases. Group 1 (wire vectis) had minimum intraoperative complications whereas group 2 had maximum.31 (10.88%)had grade 1 (minimal) difficulty intraoperetively. 25 (8.77%)cases had grade 2 (moderate) difficulty. 19 (6.67) cases had grade 3(abandoned) difficulty. Conclusion: By adjusting parameters like size of cornean incision, hydrodissection or debulking of nucleus before delivery of nucleus in different grades of hardness of cataract, a surgeon may choose any one technique in which he or she is comfortable. Manual small incision Cataract surgery with its low complication rate has now come to be established surgical procedures for cataract surgery.Keywords

Background and Objectives: Intraocular pressure increase frequently occurs in the early period after cataract Extraction. Some operated patients of cataract surgery, however, may experience pain, corneal oedema, glaucomatous nerve damage, or anterior ischemic optic neuropathy. Causes of this elevation in IOP include retained lens material, postoperative inflammation, and retention of viscoelastic substances within the anterior chamber. Postoperative increases in IOP are transient and benign. It is therefore important to monitor continuously the effect of new cataract surgical techniques on postoperative IOP as well as the impact of increased IOP on visual outcomes. Materials and Methods: Out of total patients who underwent cataract surgery at our institute 1311 had increase in intra-ocular pressure during November 2015 to October 2017. Out of those total number of 150 patients were selected at random after taking inclusion and exclusion criteria into consideration. Cases of increased intraocular pressure post cataract surgery were included in study were examined in full on observations documented on post-operative Day 1 then till discharge, after 7 days, 1 month and 3 months. Results: Thus, incidence of increase in intraocular pressure after cataract surgery in our institute is 24.15%. In the present study acute postoperative inflammation was the most common cause (39%) of increase in intraocular pressure. Other common causes were vitreous obstruction following posterior capsular rupture (27%), retained visco-elastic substances (22%). Least common cause (2%) in our study was retained lenticular fragments. Conclusion: Maximum patients (53%) with raised intra-ocular pressure post-cataract surgery had pressures in the range of 21 to 30 mm Hg. Majority (64%) had post-operative day 1 best corrected visual acuity between FC 1 m to 20/200. No patient had BCVA 20/20 to 20/40. Patients with increased IOP more than 40 mm Hg were associated poor visual outcome compared to patients with less IOP rise. In maximum patients (86%), intra-ocular pressure became normal (<21mm hg) within 7 days.Keywords

Background and Objectives: Raised intraocular pressure is a well-known causative risk factor for the development of glaucoma. It is also the only component of glaucoma that is amenable to medical or surgical intervention, provided it is detected early enough. The measurement of intraocular pressure has evolved over time with the advent of a myriad of newer tonometers – one such being the non-contact tonometer. This study has been embarked upon with the objective of comparing the non-contact tonometer with the gold standard. Goldmann applanation tonometer versus the Schiotz tonometer, one of the most popularly used tonometers in the developing world. It also aims to establish the value of the non-contact tonometer as a screening tool. Materials and Methods: 200 purposively selected patients were subjected to three methods of tonometry; Goldmann applanation tonometry, Perkins Tonometry and Schiotz indentation tonometry (with the 5.5g, 7.5g and 10g weights); on both eyes. Three recordings were obtained with each method and the arithmetic mean taken as the intraocular pressure. The data was statistically analyzed using the intra-class correlation coefficient. Results: The non-contact tonometer showed excellent agreement with the Goldmann applanation tonometer compared to the Schiotz tonometer which showed only a fair agreement. Interestingly, the left eyes showed better agreement on noncontact tonometry than the right eyes, a phenomenon we attribute to apprehension of the patients on their first experience with the air puff. The non-contact tonometer also scored high as an effective screening tool. Conclusion: The non-contact tonometer compares favorably with the Goldmann applanation tonometer and can be reliably used as a screening tool. However, in view of the varying degrees of comparison between the two eyes, its role in monitoring glaucomatous eyes needs to be further evaluated.Keywords

Background: To conduct an effective ROP screening program according to the Indian standard needs and to identify the infants who could benefit from treatment and make appropriate recommendations on the timing of future screening. Aims and Objectives: To estimate the incidence of ROP among Premature infants. Materials and Methods: A Prospective Observational study of 2 years in which 170 patients were screened with following criteria: GA at birth of ≤35 weeks, BW <1700 gms, exposed to oxygen >30days, other factors that can increase the risk of ROP and where screening should be considered are premature babies >37 weeks and >1700gms but with the first screening was done within 4 weeks (30 days) of life in infants with age >28 weeks of GA, 2-3 weeks after birth if GA <28 weeks or BW is <1200gms. Results: Out of the 170 babies screened 35 babies had ROP. Incidence of ROP in our study was 20.59%. The sensitivity of AAP and UKRCPCH guidelines to ours were 77.14% and 60% respectively. Conclusion: ROP may be seen in heavier and larger babies in India that have consequently a shorter window period for development of ROP, Hence, a criteria screening even larger babies should be taken into consideration.
