NMC EyeCare’s qualified and expert team of ophthalmologists brings to you cutting-edge technology of Bioptics to manageresidual refractive error after cataract surgery.
Bioptics is a combination of two techniques, LASIK (laser-Assisted in situ keratomileusis), and lens implantation. Your doctor may suggest bioptics for residual refractive error, when your vision does not get corrected completely after cataract surgery and if you do not wish to depend on corrective eye wear. Bioptics is recommended if you have more than 0.75 Diopters of post-operative astigmatism (blurred vision due to irregular corneal curvature). The first procedure involves creating a corneal flap and implantation of a lens in addition to your own lens. The second procedure of LASIK is performed around 6 weeks to 3 months after the lens implantation. The flap created is lifted and laser is used to make fine corrections to the refractive error.
Advantages of Bioptics over LASIK or lens implantation alone include:
- Greater predictability of refractive outcome
- Refractive error and degree of astigmatism is corrected satisfactorily beyond the limits of each procedure alone
The only disadvantage is the association of risks of the two procedures: bleeding, in case of lens implantation and dry eye and abnormal corneal bulge in case of LASIK surgery.
