Lasik Versus Icl Implantation In Managment Of Childhood Myopic Anisometropia

To compare Lasik procedure versus ICL in managment of childhood myopic anisometropia in terms of accuracy, feasibility, rate of comlications and effect on the need of future refractive procedures.

This study was conducted in the city of Zagazig during the period between 02/02/2020 till 15/01/2023.

A prospective randomized study enrolled 31 children, aged between 6 to 15 years old, with myopic anisometropia. The cycloplegic equivalent refraction of the weak eye ranged from -5 to -16 dioptre. Patients were divided into 2 groups, the Lasik group (14 eyes) and the ICL group (17 eyes). Patients were followed up at least for 2 years.

Lasik procedures were done under topical anaesthesia along with sedation in uncooperative children using AMO Star S4 Lasik console. ICL implantation was performed under general anaesthesia in all patients using EVO ICL of STAAR Surgical.

Both groups didn’t show significant complications except three cases of flab stria in the Lasik group who were managed successfully without visual affection and one case of mild reaction in the ICL group which was managed medically without any further complications or the need of surgical intervention. The Lasik group showed more accurate refractive outcome thanks for the ability to correct astigmatism if present, while ICL group showed less rate of complications, earlier rehabilitation and have the advantage of not affecting the cornea, the thing that is helpful in case another refractive surgery is needed after stabilization of refraction.

Lasik gives a more acurate solution of correction of myopic anisometropia in children, although it has it limitations and disadvantegs. Icl implantation is superior in earlier rehabilitation, can be used in high errors, preserves the cornea with no risk of dry eye or ectasia and is a reversable procedure as the implanted lens can be removed by the surgian.
