Can LASIK Improve Reading Vision?

Are you over age 40 and strug­gling to read small print with your glass­es or con­tacts? LASIK can help with that.

Mod­ern LASIK surgery can cor­rect read­ing vision prob­lems caused by pres­by­opia with a tech­nique called mono­vi­sion — where the LASIK sur­geon ful­ly cor­rects the refrac­tive errors in one eye and inten­tion­al­ly leaves the oth­er eye mild­ly near­sight­ed. The result: the ful­ly cor­rect­ed eye sees dis­tant objects very clear­ly, and the near­sight­ed eye pro­vides sharp­er near vision with­out read­ing glass­es.

If you are con­sid­er­ing this option, it’s often wise to first try mono­vi­sion with con­tact lens­es for a short peri­od to make sure you can adapt to the mono­vi­sion expe­ri­ence before pro­ceed­ing with mono­vi­sion LASIK.

Anoth­er option is mul­ti­fo­cal LASIK — a pro­ce­dure where the laser reshapes the sur­face of the eye in a fash­ion that mim­ics the appear­ance of bifo­cal or mul­ti­fo­cal con­tact lens­es. Mul­ti­fo­cal LASIK can reduce the need for read­ing glass­es, but there’s an increased risk of glare and halos after this pro­ce­dure, which may be dif­fi­cult to reverse.

Per­haps an even bet­ter pres­by­opia cor­rec­tion surgery than mono­vi­sion LASIK or mul­ti­fo­cal LASIK is corneal inlay surgery.

Mono­vi­sion LASIK is one way to improve read­ing vision. A corneal inlay is anoth­er.

In this pro­ce­dure, a laser is used to cre­ate a small pock­et in the cen­ter of the cornea of one eye, and a tiny opti­cal device (a corneal inlay or corneal implant) is then placed in this pock­et, which self-seals.

The corneal implant increas­es depth of focus in the treat­ed eye — improv­ing near vision with­out any sig­nif­i­cant loss of dis­tance vision. (This is its advan­tage over mono­vi­sion LASIK, which improves near vision but caus­es a notice­able loss of clar­i­ty of dis­tance vision in the “near” eye.)

FDA-approved corneal inlays are used by refrac­tive sur­geons in the U.S. to improve read­ing vision. The Kam­ra inlay (Acu­Fo­cus) is one of the well-known pro­ce­dures for improv­ing read­ing vision. Anoth­er device — the Pres­bia Flex­ivue Microlens (Pres­bia) — has received the CE mark, allow­ing the lens to be com­mer­cial­ly avail­able across the Unit­ed States.

A corneal inlay pro­ce­dure can be per­formed for peo­ple who have per­fect dis­tance vision with­out cor­rec­tive lens­es and just need help with pres­by­opia-relat­ed read­ing vision prob­lems. Or it can be per­formed some­time after LASIK for peo­ple who also need vision cor­rec­tion for near­sight­ed­ness, far­sight­ed­ness, and/or astig­ma­tism.
