Biometric Characteristics of the Eye With Microcornea/Microphthalmia and Congenital Cataract Before And After Cataract Extraction
Egypt133 participantsStarted 2020-07-25
Plain-language summary
Early cataract surgery in microcornea/microphthalmia eyes is essential to prevent amblyopia and improve visual outcomes, including stereopsis. However, despite recent advances in pediatric cataract microsurgical techniques, this surgery remains challenging owing to several intraoperative difficulties attributable to the crowded anterior segment in these small, soft, and poorly developed eyes with shallow anterior chambers, and poor pupillary dilation.
In this study the investigator aim to report on the changes in the anterior segment biometric characteristics after cataract extraction in eyes with microcornea/microphthalmia with congenital cataract.

Inclusion criteria
. Children presenting with congenital cataract in one or both eyes and with a horizontal corneal diameter less than 11 mm and/or an axial length less than 2 standard deviations for age of the child, less than 18mm in children under one year and less than 20mm in those less than 1year (cases).
. Children presenting with congenital cataract in one or both eyes with otherwise normal ocular biometric characteristics (controls).
Exclusion criteria
.Children presenting with congenital cataract associated with other ocular anomalies other than microcornea/microphthalmia
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
