Predictability of Intraocular Lens Calculation Using the Holladay II Formula after in-the-Bag or Optic Captured Posterior Chamber Intraocular Lens Implantation in Paediatric Cataracts

Predictability of Intraocular Lens Calculation Using the Holladay II Formula after in-the-Bag or... Purpose: To assess the predictability of postoperative refraction using the Holladay II-formula in paediatric patients randomized to undergo 2 different surgical procedures. Methods: Fourty cataractous eyes of 29 patients (age 2.31–11.75 years) were operated with in-the-bag intraocular lens implantation. Randomly, either an anterior vitrectomy (group A, 19 eyes) or posterior optic capture without vitrectomy (group B, 21 eyes) was performed. Randomization was done in 4 separate age groups, in accordance with 4 target refractions (0, 1, 2 and 3 dpt) to compensate for the anticipated myopic shift. Results: The predicted refraction correlated with the achieved postoperative refraction (total group, p = 0.019), closer in group A (p = 0.033) than in group B (p = 0.265); however, the results of groups A and B were not significantly different (p = 0.324). There was a tendency for postoperative targeted hyperopia being underachieved in the youngest patients. Conclusion: The Holladay II formula provides reliable intraocular lens calculation in paediatric cataracts. The tendency to underachieve the target refraction in younger patients needs further investigation. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Ophthalmologica Karger

Abstract

Purpose: To assess the predictability of postoperative refraction using the Holladay II-formula in paediatric patients randomized to undergo 2 different surgical procedures. Methods: Fourty cataractous eyes of 29 patients (age 2.31–11.75 years) were operated with in-the-bag intraocular lens implantation. Randomly, either an anterior vitrectomy (group A, 19 eyes) or posterior optic capture without vitrectomy (group B, 21 eyes) was performed. Randomization was done in 4 separate age groups, in accordance with 4 target refractions (0, 1, 2 and 3 dpt) to compensate for the anticipated myopic shift. Results: The predicted refraction correlated with the achieved postoperative refraction (total group, p = 0.019), closer in group A (p = 0.033) than in group B (p = 0.265); however, the results of groups A and B were not significantly different (p = 0.324). There was a tendency for postoperative targeted hyperopia being underachieved in the youngest patients. Conclusion: The Holladay II formula provides reliable intraocular lens calculation in paediatric cataracts. The tendency to underachieve the target refraction in younger patients needs further investigation.
