The change in axial length in the pseudophakic eye compared to the unoperated fellow eye in children with bilateral cataracts

“…Foreign authors, relying on age of children at the time of surgery, 4 -6 week age make calculation of IOL for receiving a refraction 8.00 dptr at babies and 6.00 dpr at babies 6 weeks of life are more senior [25]. Other authors when calculating optical power of the implanted IOL suggested to consider initial sizes of eyes.…”

Axial Length Change in Pseudophakic Eyes Measured by IOLMaster 700

“…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.…”
