Cataract Surgery After LASIK or PRK

Prior laser surgery changes the measurements

LASIK and PRK reshape the cornea. Standard methods for measuring corneal power and selecting an intraocular lens can be less accurate after that change. Your cataract surgeon should know whether the previous treatment corrected nearsightedness or farsightedness, and whether you also had an enhancement.

Old records can help, but are not always required

If you have your pre-LASIK prescription, earlier corneal measurements or the laser treatment report, bring them. Many patients do not have these records. Modern measurements and calculation methods can still help plan surgery, although there is more uncertainty than in an otherwise similar eye without prior corneal surgery.

The surface and the target matter

Dry eye, irregular astigmatism and other corneal changes can make lens measurements less consistent. A surgeon may repeat measurements or treat the ocular surface first. We then discuss which distance matters most and whether a lens design fits the corneal optics and the rest of the eye.

Plan for a range of outcomes

The intended target is an estimate, not a guarantee. Even with careful planning, glasses, contact lenses or a later refractive adjustment may be needed. A frank discussion of that possibility before surgery helps patients choose a lens and target that fit their priorities.
