To the Editor We read the article on ‘Prediction error and myopic shift after intraocular lens implantation in paediatric cataract patients’ by Hoevenaars and colleagues1 with great interest. It studied myopic shift, which is an important consideration when choosing the intraocular lens (IOL) power to be implanted in paediatric cataract patients. The authors yielded an equation using multiple regression analyses to predict myopisation (p=0.00001), and importantly pointed out that corneal radii would affect the prediction error. We had the following observations and comments.
The authors stated that preoperative axial length measurements were performed using the Alcon Ocuscan. This system has both immersion and contact capability. The authors did not state which technique they employed. In a recent study comparing axial length …
