What this Trial Is About
The long-term goal of this project is to utilize very high-speed optical coherence tomography (OCT) technology to guide surgical treatments of corneal diseases. OCT is well known for its exquisite resolution, but until recently it has not had sufficient speed to capture the shape of the cornea because of eye motion during OCT scanning. The development of Fourier-domain (FD) OCT technology has made the requisite speed possible. The objective of this project is to develop methods for imaging the cornea with an FD-OCT system that will precisely measure corneal shape and use this information to guide surgery. Cataract surgery in patients with previous laser vision correction often leads to significant near- or far-sightedness, a problem that could be resolved by using a more accurate intraocular lens power selection formula based on the measurement of corneal refractive power with OCT.

Who Can Participate
Eligibility Criteria
You may qualify if you...
- Patients seeking cataract surgery with implantation of monofocal or toric intraocular lenses (not multifocal or accommodative IOLs)
- Patients who have had previous laser vision correction procedures such as LASIK, PRK, LASEK, epi-LASIK, or radial keratectomy
- Post-laser vision correction patients may be subdivided into those with previous hyperopic or myopic correction
You will not qualify if you...
- Unable to provide informed consent
- Unable to maintain stable fixation for OCT imaging
- Unable to commit to all required study visits
- Eyes with other eye diseases such as retinal disease, glaucoma, or other conditions that may limit visual outcome after surgery
