Autorefraction measurements captured by both the Tracey and Shin-Nippon devices agree well with subjective refraction. The Shin-Nippon shows lower intratest variability.

AimTo compare intraocular lens (IOL) calculation methods not requiring refraction data prior to myopic laser-assisted in situ keratomileusis (LASIK) and radial keratotomy (RK).MethodsIn post-LASIK eyes, the methods not requiring prior refraction data were Hagis-L; Shammas; Barrett True-K no-history; Wang-Koch-Maloney; ‘average’, ‘minimum’ and ‘maximum’ IOL power on the American Society of Cataract and Refractive Surgeons (ASCRS) IOL calculator. Double-K method and Barrett True-K no-history, ‘average’, ‘minimum’ and ‘maximum’ IOL power on ASCRS IOL calculator were evaluated in post-RK eyes. The predicted IOL power was calculated with each method using the manifest postoperative refraction. Arithmetic and absolute IOL prediction errors (PE) (implanted–predicted IOL powers), variances in arithmetic IOL PE and percentage of eyes within ±0.50 and ±1.00 D of refractive PE were calculated.ResultsArithmetic or absolute IOL PE were not significantly different between the methods in post-LASIK and post-RK eyes. In post-LASIK eyes, ‘average’ showed the highest and ‘minimum’ showed the least variance, whereas ‘average’ and ‘minimum’ had highest percentage of eyes within ±0.5 D and ‘minimum’ had the highest percentage of eyes within ±1.0 D. In the post-RK eyes, ‘minimum’ had highest variance, and ‘average’ had the least variance and highest percentage of eyes within ±0.5 D and ±1.0 D.ConclusionIn post-LASIK and post-RK eyes, there are no significant differences in IOL PE between the methods not requiring prior refraction data. ‘Minimum’ showed least variance in PEs and more chances of eyes to be within ±1.0 D postoperatively in post-LASIK eyes. ‘Average’ had least variance and more chance of eyes within ±1.0 D in post-RK eyes.

Background: Dengue viral infections are the most important mosquito-borne diseases of the Indian subcontinent and have become a major global public concern. Objective: To evaluate hematological changes in serologically proven patients with clinical manifestations of dengue fever at tertiary care hospital. Materials and Methods: Cases of fever, clinically suspected to be dengue were confirmed by immunochromatographic tests for dengue NS1 antigen and dengue IgM antibody during the period from September 2015 to November 2015. A total of 250 seropositive dengue cases were correlated with clinical features, hematological, and biochemical findings. Result: With the most common clinical feature-high grade fever (95%), the main hematological findings were raised hematocrit (>29%), leukopenia (44%), and thrombocytopenia (59%). Conclusion: Hemoconcentration, leukopenia, thrombocytopenia, raised SGPT, and raised serum bilirubin gave enough clues to test for dengue serology so as to reduce the morbidity and mortality because of this disease.

Purpose: To evaluate long-term visual outcomes and complications after toric intraocular lens (IOL) implantation in children with preexisting corneal astigmatism undergoing cataract surgery. Setting: Iladevi Cataract & IOL Research Center, Ahmedabad, India. Design: Prospective, interventional case series. Methods: Children with regular corneal astigmatism of at least 1.5 diopters (D) were included. A standardized surgical technique with in-the-bag implantation of a toric IOL was performed. All children were followed up on postoperative day 1 and periodically thereafter, until 36 months postoperatively. The uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), and residual refractive astigmatism were documented 36 months postoperatively. Rotational stability of toric IOL was also evaluated through the follow-up duration. Complications, particularly visual axis obscuration (VAO) and glaucoma, were documented. Results: In total, 76 eyes (51 children) were included in the study. Mean age at surgery was 7.41 ± 2.82 years (SD) and mean preoperative keratometric astigmatism was 1.56 ± 2.13 D. The CDVA (logarithm of the minimum angle of resolution [logMAR]) improved significantly from 0.59 ± 0.43 preoperatively to 0.23 ± 0.27 36 months postoperatively (P = .03). Mean postoperative UDVA was 0.32 ± 0.26 logMAR. Mean refractive astigmatism at final follow-up was −0.55 ± 0.40 D, with 74% patients having a UDVA of at least 20/40; 5% of eyes needed VAO treatment and none developed glaucoma. No eye required repositioning of toric IOL until final follow-up. Conclusions: Toric IOL implantation reduced postoperative refractive astigmatism and gave excellent UDVA at 36 months follow-up in pediatric eyes undergoing nontraumatic cataract surgery.
