Brief Summary

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

The investigators will evaluate 30 patients with surgical indication for corneal transplantation. Participants will be divided according to the following diseases diseases: keratoconus, bullous keratopathy, corneal dystrophies. Participants will be informed about the risks and benefits of the study and sign an informed consent form. In the preoperative evaluation will be submitted to a complete ophthalmologic examination with complementary tests, such as optical coherence tomography.

One group of participants will undergo corneal surgery using the OCT Lumera microscope RESCAN - ZEISS and another group with a conventional microscope. Everyone will have their filmed and documented surgery. The team of surgeons will answer the questionnaire on the surgical difficulty about the ease of assessing corneal transplantation. After surgery, participants will be assessed on days 1, 7,15, 30, 60, 90 and 180 after surgery.

Surgeries and study procedures will be performed by the same team of surgeons and performed by IPEPO - Paulista Institute of Studies and Research in Ophthalmology / Vision Institute.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Participants will be allocated in one of the following groups:

1. Control Group The control group will undergo corneal transplant with conventional microscope without coupled OCT. The team of surgeons will answer the questionnaire on the surgical difficulty regarding corneal transplantation (ANNEX 1).
2. Group OCT RESCAN In the group microscope coupled to OCT, patients will undergo retinal surgery using the Lumera Microscope WITH RESCAN OCT - ZEISS. The team of surgeons will answer the questionnaire on the surgical difficulty regarding corneal transplantation (ANNEX 1).

The investigators will evaluate intraoperative conditions, complications, operative time and postoperative results in both groups.

All patients will be monitored and evaluated with full ophthalmological examination in all postoperative visits (day 1, 7,15,30, 60, 90, 180) and will be subjected to the following tests:

* Measurement of visual acuity with best correction
* Previous Biomicroscopy
* Corneal Topography
* tonometry
* Optical coherence tomography (OCT)
* Microscopy speculate
