“…The opposite result may be related to the impact of congenital/developmental cataracts on eyeball growth. Seven et al ( 28 ) found a lower growth rate of AL in pseudophakic eyes than in phakic eyes, while Wilson et al ( 18 ) found that eyes treated for monocular cataracts in infancy had axial growth similar to that of fellow eyes. This finding and the reasons behind it remain to be solved in further studies.…”

“…Additionally, studies have shown that the growth of AL in unilateral patients tends to be greater than that in bilateral patients ( 33 ). Children with unilateral congenital cataracts are more likely to have high myopia and great anisometropia in the long term after the operation, ( 28 ) the mean of which can be up to −3.50 D (−19.63 D–+2.75 D) at the age of five. In our study, the MS in unilateral congenital cataracts was numerically larger, but no statistically significant difference was found in MS between unilateral and bilateral congenital/developmental cataracts of each group.…”

PurposeTo investigate the impact of the pre-operative axial length (AL) on myopic shift (MS) 3 years after primary intraocular lens (IOL) implantation in congenital/developmental cataract patients.MethodsA retrospective study of patients who underwent congenital/developmental cataract surgery and primary IOL implantation at age 2–3 years at EENT Hospital was conducted. All patients were followed up regularly for at least 3 years after surgery. Refractive outcomes, including spherical equivalent (SE) and MS, were collected at each follow-up.ResultsForty eyes from 40 patients were included. The mean age at surgery was 2.56 ± 0.57 years old, and the mean follow-up time was 3.05 ± 0.22 years. Patients were divided into two groups: Group 1 included 20 patients with longer pre-operative ALs (≥22 mm), and Group 2 included 20 patients with average pre-operative ALs (<22 mm). By the last follow-up, the MS was 2.13 (0.38, 2.63) D in Group 1 and 3.88 (2.85, 5.72) D in Group 2. The post-operative MS in Group 2 was statistically greater than that in Group 1 at 3 years after surgery (P < 0.001).ConclusionIn congenital/developmental cataract patients who underwent cataract extraction and primary IOL implantation at age 2–3 years, eyes with longer pre-operative ALs had a slower MS than those with average pre-operative ALs 3 years after surgery. This finding could have implications for the target refraction decision in congenital/developmental cataract surgery.

Purpose: To evaluate the postoperative longitudinal refractive changes in children under 8 years of age with ectopia lentis and Marfan Syndrome (MFS). Setting: Zhongshan ophthalmic center, Guangzhou, China. Design: Retrospective cohort study. Methods: Medical data of patients diagnosed with ectopia lentis and MFS that underwent surgery before 8 years old were collected. Refractive errors and ocular biometric parameters were collected before surgery and at each follow-up visit. Patients were stratified into groups according to age at surgery and only the eye operated upon first was selected. Multivariable analysis was performed to determine the association between refractive shift and potential risk factors. Results: In total, 54 eyes of 54 patients were enrolled. The median age at surgery was 6.21 years (Interquartile range [IQR], 5.25 to 6.85) and the median follow-up was 2.0 years (IQR, 1.2 to 2.8 years). At 8 years old, patients demonstrated a median myopic shift ranged from -1.75 diopters (D) (IQR, -2.75 to -1.00 D) for the 4-year-old group to -0.13 D (IQR, -0.50 to -0.06 D) for the 7-year-old group. Multivariable analysis showed greater myopic shift was associated with younger age at surgery (P=0.004), male gender (P=0.026) and shorter preoperative axis length (P=0.005). Conclusion: A tendency toward increasing postoperative myopic was demonstrated in children with ectopia lentis and MFS, with the greatest myopic shift in the younger age groups. If the goal is to reach emmetropia by age 8, the immediate postoperative hypermetropic targets should be 1.75D for 4 years old, 1D for 5 years old, 0.5D for 6 years old, 0 to 0.25D for 7 years old.

“…1,2 It is a prerequisite to measure AL precisely in pseudophakic eyes in many scenarios, such as providing one of the essential biometric information in patients who require IOL exchange or a secondary piggyback IOL implantation, 3,4 or monitoring ocular development and refractive status in children or patients with high myopia. [5][6][7][8] However, precise AL measurement in pseudophakic eyes remains a challenge because IOL implantation could influence the propagation speeds of the ultrasound or light wave. AL shortening or increasing after cataract surgery measured by classical ultrasound biometry has been previously reported, and different ultrasound velocities or correction factors ranging from +0.40 mm to −0.80 mm were suggested to be utilized to eliminate this AL difference in pseudophakic eyes.…”

The purpose of this study was to investigate the change in axial length (AL) after cataract surgery measured by swept source optical coherence tomography (IOLMaster 700), and explore ways to eliminate this AL measurement error in pseudophakic eyes. Methods:Patients with cataract who underwent unilateral phacoemulsification with four types of intraocular lens (IOLs) implantation (Asphina 509M, Tecnis PCB00, enVista MX60, and Acrysof SN60WF) were enrolled. Bilateral AL measurements were performed before and 1 month after cataract surgery utilizing IOLMaster 700. The postoperative AL of the operated eye was evaluated using three different modes (phakic, aphakic, and pseudophakic), and the fellow eye was measured by phakic mode. Associations among the AL change and cataract grade, lens thickness, preoperative AL, or refractive index of IOL were investigated using stepwise multivariate linear regression.Results: A total of 305 patients with cataract with mean age of 65.97 ± 13.39 years were recruited. The mean postoperative AL was 0.10 mm and 0.21 mm shorter than the pre-operative AL utilizing pseudophakic and phakic modes, respectively (P < 0.001). No significant difference was observed between pre-operative and postoperative AL using aphakic mode (P = 0.264). There were no significant associations among AL change in pseudophakic eye and cataract grade, lens thickness, pre-operative AL, or refractive index of IOL (P > 0.05). Conclusions:A correction factor of 0.10 mm is suggested to eliminate AL measurement error of IOLMaster 700 in pseudophakic eyes before further improvement of AL measurement accuracy.
