Posterior polar cataract surgery using a femtosecond laser to femtodelineate the lens nucleus using a technique described by Dr A Vasavada

Reference: Femtodelineation to enhance safety in posterior polar cataracts. Vasavada AR et al. J Cataract Refract Surg 2015

Case history:
- 45 year old patient with posterior polar cataract
- Best corrected Visual Acuity (BCVA) = 20/40

Management:
Femtolaser assisted cataract surgery with a Vivity extended depth of focus intraocular lens utilising the femtodelineation technique:

Surgery performed in 2023 by Dr Simon Chen, Vision Eye Institute, Sydney, Australia.
