If you are functionally monocular, meaning you rely on one eye for useful vision, refractive decision-making changes fundamentally.
Laser surgery is statistically safe. But no elective corneal procedure is zero risk.
For a patient with two healthy eyes, rare complications affect one of two visual systems.
For a monocular patient, risk concentration is absolute.
Professional guidance encourages heightened caution when considering elective refractive surgery in monocular individuals. ¹
Even rare risks, infection, flap complication, ectasia, carry disproportionate consequence.
At Blue Fin Vision®, we evaluate:
- Cause of vision loss in the non-seeing eye
- Stability of the seeing eye
- Occupational demands
- Psychological risk tolerance
Some monocular patients do proceed safely after detailed counselling. Others are best managed conservatively or with reversible correction strategies.
Elective surgery requires weighing probability against consequence.
In monocular patients, consequence dominates the equation.
