RESUMO
Background:Phacoemulsification requires a smaller incision, few or no stitches are needed and the patient's recovery time is usually shorter when using a foldable IOL.Limbal Relaxing Incisions, or LRIs, are partial thickness corneal incisions strategically placed to reduce or eliminate pre-existing astigmatism duringcataractsurgeryorrefractivelensexchangesurgery. Present study was aimed to evaluate the visual and refractive outcome in patients undergoing limbal relaxing incision during clear corneal phacoemulsification surgery with foldable intra ocular lens.Material And Methods:Present study was single-center, prospective, observational study, conducted in patients of age more than 18-75 years, with clear cornea and regular astigmatism on keratometry, with preoperative astigmatism more than or equal to 0.5D on keratometry, fit for phacoemulsification cataract surgery with foldable IOL.Result:A total of 44 eyes of 44 patients who for cataract phacoemulsification surgery, mean age of the patient was 56.98 ± 05.98 years. Refractive acceptance preoperatively was 0.50 D to 2.0 D.Onslit lamp examination showed most common Cataract Nucleus grade is NS 3 with PSC preoperatively. We observed improved diopteric difference by automated keratometry on postoperative 90th day as compared to preoperative values. Majority of patients had Preop Keratometric Difference (K1-K2) of 1.5 D, all required LRI Incisions length of 4 clock hours (60°).The difference between the visual acuity preoperatively and post operatively was found to be statistically significant with a p<0.01 by employing the statistical test Analysis of Variance (ANOVA). Visual outcome a change after limb relaxing incisions statistically significant. Keratometry changes preop and postop is statistically significant with p value <0.001.Conclusion:Visual and refractive outcome changes as improved best corrected visual acuity (BCVA), decrease in Corneal Astigmatism was noted in patients undergoing limbal relaxing incision during clear corneal phacoemulsification surgery with foldable intra ocular lens
RESUMO
Background:Surgically induced astigmatism (SIA) is astigmatism that is created by incisions in cataract surgery; change in both the power and to a lesser degree, orientation of the principal meridians following a corneal incision. Prese nt study was aimed to study change in vision and astigmatic refractive error postoperativelyin patientsundergoing clear corneal phacoemulsificationsurgerywithfoldableintraocularlens.Material And Methods:Present study was hospital based, prospective, observational study, conducted in patients posted for phacoemulsification cataract surgery with foldable IOL with clear cornea and regular astigmatism on keratometry, with preoperative astigmatism more than or equal to 0.5D on keratometry, willing to participate in study.Result:In present study,44 eyes of 44 patients were considered for study. Mean age of the patient is 56.98 ± 5.98 years. There were 29 males and 15 females. Right eye surgery was done in 18 eyes and left eye surgery was done in 26 eyes. Refractive acceptance preoperatively was 0.50 D to 2.0 D. Mean IOL power was 22.7 ± 0.801. Preoperatively mainly eyes had best visual activity between 6/24 to 6/18 while visual activity range from 6/60 to 6/12. Improved vision postoperatively day 90th where vision was 6/6 unaided in 24 eyes out of44 eyes and 6/9 in 14 eyes respectively. Majority of patients had Preop Keratometric Difference (K1-K2) of 1.5 D, all required LRI Incisions length of 4 cloc k hours (60°). On postoperative 90th day, improved dioptric difference by automated keratometry ascompared to preoperative values. LRI was slightly more effective in patients above 50 years as compared to in patients below 50 years.Conclusion:In patientsundergoing clearcornealphacoemulsification surgery with foldable intra-ocular lens, postoperatively improved vision and reduced astigmatic refractive error is noted.
RESUMO
Background:Aim&Objective:To study the epidemiology of vitreous hemorrhage in patients presenting without retinal detachment. To study various etiology of vitreous hemorrhage. To study visual outcome in patients with non resolving vitreous hemorrhage required vitrectomy surgery. To study prognostic factors (age, sex,andvitreous hemorrhage in diabetic patients, hypertensivepatients, ARMD, Ealesdiseases) affecting visual outcome in vitreous hemorrhage. Material And Methods:Study included34patients out of which 13 have diabetes, 6 have hypertension, 7have both diabetes and hypertension, 6have past history of tuberculosis and 2 have no systemic illne ss. Examination includedpreoperative and postoperative best corrected visual acuity, slit lamp examination, intraocular pressure, ultrasound B scan and dilated funduswith indirect ophthalmoscope. Result:Majority patients (38. 2%) were in the age group of 51-60 years with the mean age 51. 35 years. Males [73. 5%] had higher incidence of vitreous hemorrhage than females and Incidence of vitreous hemorrhage was higher in lower socio-economic group. Diabetes Mellitus andHypertension werethe most common co-morbidities with Proliferative diabetic retinopathy,Eales diseases and Branch Retinal vein occlusion are the important Risk factors for vitreous hemorrhage. Most common presenting symptom of vitreous hemorrhage is sudden loss of vision [52. 9%] followed by gradual loss of vision and blurring loss of vision. Patients who received pan retinal photocoagulation and Anti-vegf have better visual outcome post-operativel. Pan retinal photocoagulation, Epiretinal membrane, traction band,macular edema,andchoroidalneovascular membrane are the intraoperative findings noted intra-operatively. Preoperatively most of the cases of vitreous hemorrhage had visual acquity in the group of Perception of light and finger counting close to face. Post-operatively 15 patients have visual acuity in group of 6/18-6/9. Among them 8 were PDR,4 cases of Eales disease and 3 were BRVO cases. Visual acuity of 8 cases belongs to group of 6/60 –6/24 which include 5 PDR , 2 BRVO and 1 Ealesdisease. Post-operatively 7 patients developed complications. Raised IOP seen in 3 cases which includes 2 PDR cases and 1 Eales disease. Cataractous lens noticed in 2 PDR cases. Retinal detachment developed in 1 PDR case. Revitreous hemorrhage occurred in 1 Eales disease. 2 cases underwent re-surgery. Revitrectomy done in 1 case of Eales disease for re-vitreous hemorrhage. Re-vitrectomy with silicone oil insertion done in 1 PDR case for retinal detachment. Conclusion:Visual impairment due to Vitreous hemorrhagemay be prevented by early detection of cause by appropriate investigations and treatment.
