Informed consent
On attending the screening clinic, potentially eligible participants and their parents (or legal guardians) will be approached by a trained research coordinator to determine whether they want to participate in the trial. If they express their interest, the researcher will gain informed consent and recruit the patient. Written informed consent will be obtained from the parent or legal guardian before performing the standard clinical surgical treatment. Once the patient is enrolled in the study, he/she will be assigned to either the capsular group or the sulcus group. When the participants reach 18, they should re-consent.
