Treat The Vision, Not The Scar”: A Functional Non-Surgical Strategy For Visual Rehabilitation In Corneal Opacity

To assess whether vision in patients with visually significant corneal opacity can be rehabilitated using non-surgical functional modulation rather than corneal transplantation.

Prospective interventional study conducted in private tertiary ophthalmology referral centers specializing in corneal disease.

Prospective interventional case series including patients presenting with visually significant corneal opacity not immediately suitable for keratoplasty (post-infectious scars, stromal fibrosis, and traumatic opacities).

Optical Axis Modulation

• Short-acting pharmacologic pupillary dilation once or twice daily to redirect the visual axis toward clearer paracentral cornea

Pharmacologic Stromal Remodeling

• Topical Losartan 0.08% q.i.d.
• Ocular surface stabilization with lubricants
• Short, monitored anti-inflammatory pulse when active haze

Patients were followed serially to document visual performance rather than slit-lamp appearance.

Primary outcome: change in corrected distance visual acuity.

Most patients demonstrated measurable visual improvement despite minimal change in the apparent density of corneal opacity.

Therapeutic dilation produced immediate functional visual gain by shifting the visual axis toward clearer corneal zones.
Topical Losartan showed progressive improvement over weeks, with reduction of fibrotic haze and improved visual quality rather than dramatic slit-lamp clearing.

Several patients achieved satisfactory daily-activity vision and elected to defer keratoplasty.

Visual performance improvement was frequently disproportionate to anatomical change, emphasizing that optical pathway modulation and fibrosis remodeling improved function even when corneal opacity remained clinically visible.

Visually significant corneal opacity should not automatically lead to surgical planning.
Functional vision can be meaningfully improved through a combined strategy of optical axis redirection using therapeutic mydriasis and pharmacologic stromal remodeling with topical Losartan 0.08%.

Visual recovery was often disproportionate to anatomical clearing, indicating that restoring light transmission through clearer corneal zones and modifying fibrosis can rehabilitate vision even when opacity persists clinically.

This approach provides a safe, repeatable, and accessible pathway to delay or avoid keratoplasty, shifting management from tissue replacement toward functional visual rehabilitation.
