Summary
The Kamra corneal inlay allows clear visualization of the central and peripheral retina. This study confirms good quality retinal imaging and optical coherence tomography (OCT) scans after inlay implantation.
Area of Science:
- Ophthalmology
- Biomedical Engineering
Background:
- The Kamra corneal inlay is a device implanted in the cornea to improve near vision in patients with presbyopia.
- Assessing the impact of corneal inlays on posterior segment imaging is crucial for patient management and follow-up.
Observation:
- Two cases of Kamra corneal inlay implantation were evaluated.
- Retinal visibility and optical coherence tomography (OCT) scan quality were assessed under pharmacological mydriasis by an experienced retinal ophthalmologist.
- Central and peripheral fundus examination was performed.
Findings:
- Central and peripheral retinal visualization was not disturbed by the inlay.
- Peripheral retinal imaging showed accurate results with a minor bright shadow artifact.
- Optical coherence tomography (OCT) scans demonstrated good quality for macular line, 3-dimensional cube, and radial protocols in both patients, with no scanning artifacts attributed to the inlay.
Implications:
- The Kamra corneal inlay permits normal visualization of the entire fundus.
- The inlay does not compromise the quality of standard retinal imaging or OCT scans.
- These findings support the safety and efficacy of the Kamra inlay concerning posterior segment evaluation.
