Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

Obtaining appropriate mydriasis prior to cataract surgery is an important variable in successful surgery. The current practice includes using topical anticholinergic and sympathomimetic agents in the preoperative area prior to cataract surgery, but the pupils are sometimes insufficiently dilated and can often need additional mydriasis with intracameral agents during cataract surgery. Pre-operative topical mydriatic drops take time to take effect, are mildly uncomfortable for the patient, and have a cost to the healthcare system. If intracameral mydriasis alone can achieve adequate pupil dilation, perhaps topical mydriatics would not be needed. The purpose of this study is to evaluate whether topical versus intracameral versus topical + intracameral mydriasis is the optimal way to dilate pupils during routine cataract surgery. The results of this study have implications for improving the efficiency and reducing time prior to cataract surgery. In addition, it has significant potential to reduce the cost associated with cataract surgery if preoperative drops can be eliminated.

Investigators

The overall officials registered on this study. Names that resolve to a findmyKOL profile link to it; the rest are shown as registered.

A profile link is shown only when the registered name resolves to a person record with a confident, namesake-checked match; ambiguous names stay unlinked.

Sites

1 registered facility, with the per-site recruitment status where the registry publishes one. ClinicalTrials.gov does not publish per-site enrollment counts.

Site investigator names are published by ClinicalTrials.gov only while a study recruits, so completed studies list sites without them.
