Can lens replacement surgery be done twice? Lens replacement is permanent. You will not relapse in presbyopia (ageing eyes) or get cataracts as we\u2019ve removed your natural, hardening lens with an artificial IOL (Intraocular lens). In some instances, however, we can redo your lens replacement surgery. If you need fine-tuning If you want to upgrade your monofocal lenses to multifocal lenses1, it\u2019s perfectly acceptable to ask your surgeon. We can also fine-tune your vision with laser vision correction if we expect it to improve your results.. Should the unexpected occur For some, accidents happen, and if you injure your eye after we\u2019ve replaced your lenses, we may need to redo your procedure. In fact, 3%2 of patients who\u2019ve undergone lens replacement for cataracts have experienced spontaneous dislocation. We can fix this with treatment. In case your results don\u2019t meet your expectations While rare, side effects that affect vision quality after surgery can happen. Some patients have experienced blurriness, double vision or seeing halos following their surgery. Some patients, for instance, find they can\u2019t tolerate a trifocal lens while driving at night. If that happens, we can resolve this situation by replacing the trifocal IOL with another lens (e.g. an Extended Depth of Focus) to address these night vision disturbances. Lens replacement surgery is becoming a more common and safe treatment for vision problems. Book a free assessment with us if you\u2019d like to discuss this further.
