Eyes that have undergone ICL surgery require careful consideration when intraocular lens power is calculated later in life. Although the cornea remains unaltered, some standard assumptions used in routine formulas may not apply perfectly. ¹
Modern clinics use high-resolution optical biometry, advanced calculation formulas, and multiple cross-checks to improve accuracy. ² Precise measurement of axial length, anterior chamber depth, and lens thickness is essential, and results are often compared across several formulas rather than relying on a single value.
Prior ICL surgery does not inherently compromise calculation accuracy when handled correctly. The greatest risk comes from oversimplified methods or outdated approaches. ¹
In premium IOL planning, historical refraction and implant details further refine outcomes, reducing refractive surprise and improving patient satisfaction. ²
