When residual refractive error persists after cataract surgery, two main enhancement options are available: laser vision correction applied to the cornea, or a supplementary intraocular lens, known as a piggyback lens, implanted in front of the existing implant. Choosing between them depends on the individual eye rather than patient preference alone.
Laser enhancement is generally preferred when corneal thickness is adequate, the residual prescription is predominantly spherical or astigmatic, and the patient’s corneal topography is regular. ¹ ³ It is performed without returning to theatre and recovery is typically rapid.
A piggyback lens is considered when laser treatment is unsuitable, for example in eyes with thin corneas, irregular corneal surfaces, or high degrees of residual error that would require significant corneal tissue removal. ² It involves a brief return to theatre but avoids any alteration to corneal anatomy.
At Blue Fin Vision®, the choice between these options is made following a structured postoperative assessment that includes corneal imaging, repeat biometry and ocular surface evaluation. Both approaches are available within the same surgical network, ensuring that the decision is guided by clinical findings rather than equipment availability.
