“…There was an increase in central corneal thickness 1-year post surgery when compared with the immediate postoperative period. These results are consistent with the results of earlier studies 22–24. While the myopic shift was significant in pseudophakes, a significant change in axial length was noted in both groups; similar to the IATS study 25.…”

ObjectiveTo evaluate visual outcomes and complications of infantile cataract surgery through a 1-year follow-up period in a real world scenario.Methods and analysisProspective observational study evaluating infants with cataract undergoing surgery.ResultsWe analysed 173 eyes of 97 infants (76 bilateral); median age 18.7 weeks, (IQR: 11–33.9 weeks). Toxoplasmosis, rubella, cytomegalovirus and herpes infection was the most common aetiology in both unilateral 10 (47.6%) and bilateral 43 (55.1%) cases, followed by familial and syndromic cases. Fifty-four eyes (29.5%) received primary intraocular lens (IOL) implantation.Seventy-five infants (76%) were less than 6 months of age. At 1-year follow-up, mean log MAR best-corrected visual acuity was 1.00±0.08 and 1.21±0.03 in unilateral and bilateral cases respectively (p=0.012), which was not statistically significant. At 1-year follow-up, pseudophakic(1.09±0.05) eyes had a better mean log MAR visual acuity comparing aphakes(1.24±0.04) clinically but was not statistically significant after the application of Bonferroni correction (p=0.012). The mean myopic shift of −2.9 D±0.39 and −4.53 D±0.55 over 1 year was noted in aphakes and pseudophakes, respectively (p=0.016). Visual axis opacification and glaucoma were the most common complications noted in pseudophakes and aphakes, respectively.ConclusionPrimary IOL implantation in selected cases of infantile cataract is a feasible option, particularly in cases when optimal aftercare and refractive rehabilitation of aphakia are not possible.

“…There are several studies regarding corneal thickness in children but comparative studies are very rare. In the reports, the range of corneal thickness changes from 529 to 564 µm and the average is likely 550 µm (Faramarzi et al 2010;Bradfield et al 2011;Fern et al 2012;Resende et al 2012;Sahin et al 2008;Coste et al 2008;Hussein et al 2004;Mendes et al 2011). In our study, central corneal thickness is 548 µm in the study group and 559 µm in the control group.…”

“…At present, all IOL power calculation formulas applied in children have been derived from studies conducted on adult eyes [ 3 , 4 ], children originally owning the characters of short axial length (AL), high keratometry ( K ) value, and shallow anterior chamber depth (ACD) [ 5 ], and these parameters change as children grow [ 6 ]. All these make it harder to select a proper formula to calculate IOL power [ 7 – 9 ]. Therefore, conducting research on different age groups was essential to compare the accuracy of formulas.…”

Purpose. This study aims to compare the accuracy of five intraocular lens (IOL) power calculation formulas (SRK/T, Hoffer Q, Holladay 1, Haigis, and Holladay 2) for pediatric eyes in children of different ages. Methods. In this prospective study, patients who received cataract surgery and IOL implantation in the capsular bag were enrolled. We compared the calculation accuracy of 5 formulas at 1 month postoperatively and performed subgroup analysis with the patients divided into three groups according to their ages at the time of surgery as follows: group 1 (age ≤ 2 years, 35 eyes), group 2 (2 years < age < 5 years, 38 eyes), and group 3 (age > 5 years, 29 eyes). Results. 75 patients (102 eyes) were enrolled in this study. The Haigis formula got the smallest PE among all formulas in all three groups. With regard to APE, there were no statistical differences among the formulas except group 2, with the SRK/T formula a little smaller, the Holladay 2 formula a little larger in group 1, and the Haigis formula a little smaller in group 3. In group 2, the Haigis formula had the lowest APE (0.87 ± 0.61 D), while the Holladay 2 formula had the largest (1.71 ± 1.20 D, p<0.001), followed by the Holladay 1 formula (1.51 ± 1.07 D, p=0.002). On comparing the percentage of APE within 0.5 D and 1.0 D obtained with 5 formulas in each group, there were no statistical differences. The SRK/T formula and the Holladay 1 formula showed the highest percentage (40.00% and 60.00%) in group 1. While the Haigis formula got the highest percentage in less than 0.5 D (34.21%) and less than 1 D (60.53%) in group 2. In group 3, the Holladay 2 formula and the Haigis formula got the highest percentage less than 0.5 D (58.62%) and less than 1 D (79.31%). The multiple linear regression indicated that the age at the time of surgery was a significant factor affecting the accuracy of APE; after removing the age, AL was the only factor that affected the accuracy of APE. Conclusion. The SRK/T and the Holladay 1 formulas were relatively accurate in patients younger than 2 years old, while the Haigis formula performed better in patients older than 2.
