When a patient reports blurred vision after cataract surgery, the appropriate response is not to assume a refractive cause and proceed directly to enhancement. The appropriate response is to diagnose. At Blue Fin Vision®, a structured postoperative assessment pathway is followed in every case where visual outcomes are not as expected.
The assessment begins with the ocular surface. Tear film stability is evaluated and dry eye disease is identified or excluded before any optical measurement is made. Refractive data obtained from an unstable ocular surface is unreliable, and proceeding to enhancement on the basis of such measurements risks targeting the wrong prescription. ²
Once the surface is confirmed as stable, repeat biometry and refraction are performed and compared against the original surgical targets. ¹ Corneal topography assesses regularity of the corneal surface and identifies any induced astigmatism. If the intraocular lens is toric, its current axis is verified against the intended alignment.
Retinal optical coherence tomography is performed where central visual acuity is reduced or where the pattern of symptoms suggests macular involvement. This identifies or excludes cystoid macular oedema, epiretinal membrane and other retinal pathology that would limit the benefit of any refractive enhancement.
Only once this pathway is complete, and the cause is clearly identified, is an enhancement decision made. ³ Diagnosis before intervention is not a formality. It is the basis of every recommendation we make.
