A comparative study to evaluate the effect of various postoperative treatment protocols on dry eye and patient satisfaction after phacoemulsification.

Purpose: Foreign body sensation and irritation are common after cataract surgery, as is the exacerbation of dry eye disease if present. This study compared postoperative dry eye treatments and patient satisfaction. Methods: Age-related cataract patients undergoing phacoemulsification were recruited and were divided randomly into 4 postoperative treatment groups: Group A: Antibiotic + Steroids; Group B: Antibiotic + Steroids + Mydriatic; Group C: Antibiotic + Steroids + Mydriatic + Non-steroidal Ant-inflammatory drugs (NSAIDs); Group D: Antibiotic + Steroids + Mydriatic + NSAID + Tear substitute. Patients were assessed at 1, 3, and 5 weeks post-operatively for uncorrected distance and near vision, best corrected visual acuity (BCVA) for distance and near, Schirmer's-1 test, and Tear Film Break-Up Time test. At each visit, patients were assessed for dry eye-related subjective parameters using Ocular Surface Disease Index questionnaire. Results: Study participants numbered 163. (87 male and 76 female patients). No statistically significant difference was present in visual acuity for near and distance. The mean values of Schirmer's test and TFBUT were better in group D patients at each postoperative visit, with significant differences noted in comparison with other groups. The patient response to pain and dry eye symptoms was superior in groups C and D, with group D producing the best results. Compared to group A, patients in groups C and D were more satisfied with their vision and surgery. Conclusion: The addition of tear substitutes to steroids and NSAIDs has been associated with decreased dry eye-related symptoms and a better subjective feeling of vision, although no significant difference was noted in vision measured objectively.

An insight into the altered ophthalmic dynamics during the COVID-19 pandemic.

Purpose: The objective of this survey-based study was to examine the effects of personal protective measures taken at the level of instrument and surgeon during the pandemic on the optics in ophthalmology. Methods: The study involved an online questionnaire of 24 questions which was distributed to ophthalmologists practicing in several hospitals, including residents and fellows undergoing training in ophthalmology in India. The responses were collected through an online data collection tool (Google forms). The participants could choose from multiple options provided to them in each question. Results: A total of 285 participants out of 296 had used modified methods for examining and performing surgical procedures during the pandemic, while 78.7% (265) of the participants acknowledged having encountered difficulty in interpreting the ocular findings of patients while examining in personal protective equipment. Moreover, 58.7% (198) of our study respondents also reported that there was significant worsening of the quality of ophthalmological examination with pandemic-appropriate measures and 84.8% (286) of our study participants also felt that these measures have significantly added to the time of examination, hence increasing the risk of exposure to both patient and doctor. Conclusion: The workplace study has highlighted the crucial aspects of optics in ophthalmology during the pandemic. The protective measures taken during the pandemic have significantly worsened the quality of ophthalmological examination and increased the time taken to perform outpatient department-based and surgical procedures in ophthalmology.

Comparative study of anatomical and functional recovery of eye along with patient satisfaction score after small-incision cataract surgery and phacoemulsification cataract surgery.

Purpose: Functional recovery after cataract surgery depends on the anatomical recovery of the eye. This study compared the improvement in visual function parameters after uniocular manual small-incision cataract surgery (MSICS) and phacoemulsification cataract surgery. Methods: This study included 310 patients divided randomly into two groups: 155 who received MSICS (MSICS group) and 155 who underwent phacoemulsification (phaco group) for cataract treatment. Outcome measures assessed included vertical and horizontal keratometry reading. The mean corneal astigmatism tear function measured using Schirmer 1 test results were recorded preoperatively, and on postoperative day 1, day 7, and day 30. Optical coherence tomography (OCT) was done to record the average central macular thickness (µm) on day 7 and day 30. Results: The mean corneal astigmatism and anterior chamber inflammation were more in the MSICS group than in the phaco group immediately postoperatively. However, no statistically significant difference was found between the groups with respect to corneal sensation, mean corneal astigmatism, tear film function, and visual outcomes on postoperative day 30. Uncorrected visual acuity was better in the phacoemulsification group than in the manual SICS group on postoperative day 1, day 7, and day 30 (P < 0.001). Conclusion: Both phacoemulsification cataract surgery and manual small-incision sutureless cataract surgery (MSICS) are safe and effective for visual rehabilitation. Phacoemulsification is the preferred technique where resources are available with the advantages of less mean corneal astigmatism, less anterior chamber inflammation, and better uncorrected visual acuity (UCVA) in the immediate postoperative period.

A Long-term Clinical Study to Evaluate AGV with Concurrent Intravitreal Ranibizumab vs Primary AGV Implantation in Cases of Refractory Neovascular Glaucoma.

Purpose: This study was aimed to gauge the efficacy of primary AGV implantation with concurrent intraoperative intravitreal ranibizumab vs primary AGV implantation alone in the management of neovascular glaucoma (NVG). Methods: This retrospective comparative study was carried out based on the data collected in patients of neovascular glaucoma who underwent Ahmed Glaucoma Valve implantation with or without concurrent intravitreal ranibizumab between the period from Feb 2009 to Feb 2015 involving two groups of 40 patients each, having the clinical diagnosis of neovascular glaucoma, having undergone pan-retinal photocoagulation with minimum 03 intravitreal injections of ranibizumab not less than 4 weeks prior to undergoing primary Ahmed glaucoma valve implantation and allotted randomly to either group to receive concurrent administration of intravitreal ranibizumab with Ahmed glaucoma valve (AGV) implant surgery or AGV implant surgery alone. The minimum qualifying follow-up was 3-years. The functional outcome measures included intraoperative and postoperative complications, intraocular pressure (IOP), and the need for antiglaucoma medication, if any, as well as best corrected visual acuity. Results: Both the groups showed a significant decrease in IOP (p < 0.05). Sight and IOP threatening postoperative complications were significantly low in the study group. NVI regression was higher in the study group and re-emergence was significantly lesser in the study group (p = 0.002). Mean postop IOP had shown an excellent reduction in IOP up to 14.25 ± 2.05 mm Hg with 1.5 ± 1 antiglaucoma drugs in ranibizumab group and 15.25 ± 2.95 mm Hg with 1.7 ± 0.87 antiglaucoma drugs in the control group at the 3-years follow-up period. Surgical success rates were comparable between the two groups at 1 and 3-year. Conclusion: Concurrent intravitreal ranibizumab along with primary AGV implantation minimizes postoperative complications, regresses NVI while accelerating stabilization of IOP and visual functions.

An observational study on ocular manifestations in patients of psoriasis in a tertiary care hospital in western India.

Background: The aim of the study is to observe the ocular manifestation in patients of psoriasis. Methods: All the diagnosed cases of Psoriasis by the dermatology department of this tertiary care hospital were included in this study. Relevant details of the history pertaining to disease duration, type of psoriasis, and treatment undertaken including ocular symptoms were obtained. Disease severity was quantified using the PASI score. Complete ocular examination including intraocular pressure, Schirmer I and II tests, Tear Film Breakup Tme (TBUT); was carried out for all the patients. Results: Of 126 patients of psoriasis, ocular manifestations were seen in 76 patients (60.3%). Dry eyes (27%) and blepharitis (15.9%) were the most common ocular manifestations. Uveitis was seen in 3.2% of the patients of which 75% patients were HA B27-positive psoriatic arthritis, which was statistically significant (p = 0.001). There was no statistical correlation between duration of the disease and ocular manifestations (p value is 0.077 using chi square test). The ocular manifestations were more common in patients with PASI score 10 when compared with the patients with PASI score 10 (p value = 0.028) which was statistically significant. Conclusions: In our study, prevalence of ocular manifestation was 60.3% which increased with the increasing PASI score. Dry eyes and blepharitis were the most common manifestations. Hence, routine ocular examination is recommended in patients with psoriasis.

Clinical study to estimate correlation between graft thickness as measured by anterior segment Optical Coherence Tomography and visual recovery after manual Descemet stripping endothelial keratoplasty.

Purpose: To estimate the correlation between graft thickness as measured by anterior segment Optical Coherence Tomography and visual recovery after manual Descemet stripping endothelial keratoplasty. Design: Prospective observational study. Materials and methods: This prospective observational study included 25 patients with pseudophakic bullous keratopathy, who underwent DSEK. Visual acuity in LogMAR units and estimation of graft thickness measured by Anterior Segment Optical Coherence Tomography (AS-OCT) was carried out on postoperative day 1, 3rd month and 6th month. Correlation analysis was performed between graft thickness and postoperative visual acuity on postoperative day 1, 3rd month and 6th month. Results: The mean LogMAR visual acuity improved in all patients post DSEK - 1.47 (±0.48) to 0.75 (±0.38) LogMAR units. The average postoperative day 1 central corneal thickness was 724.96 µm (±77.59 µm), which decreased to mean central corneal thickness of 655.56 (±61.08 µm) on 3rd month and 633.48 (58.72) by the 6th month. Mean donor graft thickness on postoperative day 1, 3rd month and 6th month in this study was found to be 169.3 µm (±36.6 µm), 135.9 µm (±29.8 µm) and 127.5 µm (±31 µm) corresponding to a BCVA of 1.94, 0.86 and 0.75 LogMAR units respectively. On correlation analysis, thinner grafts were found to be associated with better postoperative BCVA especially on the 3rd and 6th month follow-up period. Conclusion: This study found that a higher proportion of thinner grafts achieved better postoperative visual rehabilitation and earlier stabilization of visual acuity.

Evaluation of primary Ahmed Glaucoma valve implantation in post-traumatic angle recession glaucoma in Indian eyes.

PURPOSE: To highlight the efficacy of primary Ahmed glaucoma valve implantation in angle recession glaucoma following blunt ocular trauma in Indian eyes. DESIGN: A retrospective analytical study. MATERIALS AND METHODS: This study included 52 patients of angle recession glaucoma, who presented between Mar 2006 to Feb 2016, out of which 38 patients had undergone primary AGV implantation, while the rest were managed with topical anti-glaucoma medications. Preoperative data included age, sex, type and mode of injury, duration of injury, assessment of best-corrected visual acuity (BCVA) and intraocular pressure (IOP). The extent of angle recession was observed by gonioscopy. The intraocular pressure, visual acuity, and the number of anti-glaucoma medications were measured postoperatively. The success of this technique was analyzed by using a Kaplan-Meier cumulative survival curve. RESULTS: Following AGV implantation, the mean IOP was significantly reduced to 8.7 ± 2.2 at 1st day, 10.1 ± 2.2 at 7th day, 14.2 ± 3.4 at 3rd month, 15.6 ± 3.7 at 1 year, and 15.6 ± 3.6 at 3rd-year follow-up showing statistically significant values (p < 0.001) at each visit. The IOP was successfully controlled at the last follow-up without topical treatment. Mean BCVA at 3 years -post-AGV was 0.144 (0.151) (LogMAR) which was statistically significant (p < 0.001) as compared to the mean BCVA of 0.898 (± 0.205) LogMAR units at presentation. The success rate by Kaplan-Meier survival curve analysis was 90% at the mean follow-up duration of 29.47 ± 3.39 months. Overall surgical complications were noted in the form of prolonged hypotony, hyphema in 7 patients (13.5%). CONCLUSIONS: In medically uncontrolled post-traumatic angle recession glaucoma, primary AGV Implantation is a safe and effective surgical procedure with lesser complication rates providing long-term IOP control in a younger population.

Descemet Stripping Endothelial Keratoplasty in Microcornea for Pseudophakic Bullous Keratopathy With Anterior Chamber Intraocular Lens.

To report a case of bilateral pseudophakic bullous keratopathy (PBK) in a patient having bilateral microcornea with pre-existing anterior chamber intraocular lens (ACIOL) who underwent Descemet stripping endothelial keratoplasty (DSEK) with a successful postoperative visual outcome. A 36-year-old female, diagnosed with microcornea and congenital cataract in both eyes underwent lens aspiration sequentially followed by ACIOL implantation in both eyes. The patient reported to our centre and was diagnosed with bilateral PBK with ACIOL with microcornea. She also had associated secondary glaucoma, postoperative chronic uveitis, and hyphaema, which were controlled with medical management first and taken into consideration while planning DSEK. The patient underwent manual DSEK without intraocular lens exchange under local anaesthesia in both eyes sequentially with a good visual recovery postoperatively in both eyes. Descemet stripping automated endothelial keratoplasty (DSAEK)/DSEK seems a viable option in patients with microcornea who develop PBK following cataract surgery with retained ACIOL where there is absence of capsular support as well as deficiency of iris tissue.
