Cataract surgery nowadays is also 'refractive surgery' ie, it aims to minimise refractive errors (long/shortsightedness and astigmatism), or perhaps to target a certain refractive error like low myopia depending on the individual patient's preferences.
In this way, cataract surgery aims to achieve something similar to what LASIK does for people who do not have cataracts.
This is possible because cataract surgery replaces the original lens of the eye with a new lens implant, which comes in various focusing powers and can be tailored according to the patient's needs.
The customization/ lens implant selection is based on calculations, which are in turn based on measurements like the length of the eyeball and the curvature of the cornea.
Although a certain post-operative spectacle power may be targeted, sometimes the final achieved spectacle power is different from what was originally planned.
If you had targeted close to zero power but are now myopic, you have a few options.
You should consider several aspects of your situation first.
How myopic are you currently after the cataract surgery? If you are only slightly or mildly myopic, it might be good to leave it alone, especially if you have a monofocal lens implant, because mild myopia helps your near vision. But if you have a multifocal lens implant, mild myopia may negate the whole purpose of having this lens because it makes distance vision blurred. In this case, you might want to consider the various options to clear away this myopia.
Residual myopia can be treated like any other myopia in general. ie you can wear glasses, wear contact lenses, or consider some type of refractive eye surgery.
The possible refractive eye surgeries would include LASIK, a piggyback lens implant, or possibly a lens implant exchange.
Which you should go for depends very much on the factors mentioned above as well as your own individual preferences. Do see an eye doctor for a comprehensive eye examination, and then have a frank discussion with him or her about the risks and benefits, pros and cons of each option.
