Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is an observational study using optical coherence tomography (OCT) technology to quantify corneal edema in Fuchs' endothelial dystrophy and predict refractive shift from resolving corneal edema after surgical treatments.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Group A: No Surgery Group

This group consists of adults ages 18 or older who have been diagnosed with Fuchs' dystrophy or pseudophakic bullous keratopathy but do not require surgery per standard-of-care guidelines.

No interventions assigned to this group

Group B: Surgery Group

This group consists of adults ages 18 or older who have been diagnosed with Fuchs' dystrophy or pseudophakic bullous keratopathy, who require Descemet's Stripping Endothelial Keratoplasty (DSAEK), Descemet's Membrane Endothelial Keratoplasty (DMEK), or Descemet's Stripping Only (DSO) surgery. All treatment decisions will be made by the attending physician based on standard-of-care guidelines. (The study does not designate a treatment modality or pay for the treatment.)

No interventions assigned to this group

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Damaged or diseased corneal endothelium from Fuchs' or PBK
* Willingness to commit to required study visits

Exclusion Criteria

* Prior Endothelial Keratoplasty (EK) or any other surgery except uncomplicated cataract surgery
* Presence of a condition that increases the probability for treatment failure (e.g., heavily vascularized cornea, uncontrolled uveitis)
* Other primary endothelial dysfunction conditions (e.g., posterior polymorphous corneal dystrophy and congenital hereditary corneal dystrophy, iridocorneal endothelial syndrome)
* Central sub-epithelial or stromal scarring that could impact post-operative clarity assessment
* Peripheral anterior synechiae in the angle greater than 3 clock hours
* Hypotony
* Uncontrolled glaucoma
* Visually significant optic nerve or macular pathology
