This episode is essential for ophthalmologists and retina surgeons. It covers refractive surprise and IOL calculation after vitrectomy.
We review a real case from Dr. Riquelme and Dr. Maldonado, specialists at ENFOCA.
Treatment with vitrectomy and gas (C3F8) caused an unexpected myopic shift. This resulted in functional monovision that left the patient very satisfied.
Technical Keys for Practice
- Cause of the myopic shift: It occurs because of gas pressure in the eye. The IOL shifts forward, altering the final refraction.
- Biometric strategy: Strategy is crucial to offset the error. In uncomplicated eyes, aim for the first hyperopic value (positive target). This minimizes residual myopia after surgery.
- Advanced formulas: Use advanced formulas such as Barrett II or Kane. This gives you maximum precision in the biometry of vitrectomized eyes.
- Functional focus: The goal is functional success, not just anatomical success. Consider premium options, such as a monofocal plus lens, for the fellow eye.
