Dr. Amar Agarwal’s pinhole pupilloplasty offers an elegant optical solution for patients with severe corneal scarring, where traditional refractive correction is limited by irregular astigmatism and reduced contrast sensitivity. The principle is to create a small, well-centered pupil that functions as a pinhole aperture, allowing only the most focused central rays onto the retina while blocking distorted peripheral light passing through scarred corneal zones. In practice, the technique relies on four-point pupillary suturing to achieve a stable, round, and small aperture, typically around 1.5 mm, without excessively compromising retinal illumination. Intra-operatively, careful centration relative to the visual axis is crucial to optimize visual outcomes, especially when corneal landmarks are distorted. A cohesive OVD helps maintain chamber stability, and gentle tissue handling prevents sphincter damage. The result is often a striking improvement in functional vision, reducing glare and monocular diplopia. While not curative for corneal pathology, pinhole pupilloplasty can restore meaningful clarity when other optical modalities fall short.
