Everything You Should Know About Custom Wavefront Lasik

LASIK, which stands for Laser-Assist­ed In Situ Ker­atomileu­sis, is a laser vision cor­rec­tion pro­ce­dure that tar­gets cornea in order to cor­rect com­mon vision prob­lems such as near­sight­ed­ness, far­sight­ed­ness, and astig­ma­tism. Often referred to as Cus­tomVue LASIK or cus­tom wave­front LASIK, this is one of the most fre­quent­ly per­formed types of refrac­tive surgery thanks to its great results as well as min­i­mal down­time.

What Is Custom LASIK?

Cus­tom wave­front LASIK, com­mon­ly called just wave­front LASIK or cus­tom LASIK, uti­lizes the advanced wave­front tech­nol­o­gy to assess the indi­vid­ual and unique char­ac­ter­is­tics of the patient’s eyes. In that respect, LASIK wave­front is a more per­son­al­ized pro­ce­dure com­pared to con­ven­tion­al LASIK vision cor­rec­tion surgery; hence the name “cus­tom”.

Essen­tial­ly, Cus­tomVue LASIK doesn’t only rely on eye­glass­es pre­scrip­tions; many peo­ple can share the same pre­scrip­tion yet the unique char­ac­ter­is­tics of their eyes can make a con­sid­er­able dif­fer­ence in the clar­i­ty of their vision. This is why cus­tom LASIK relies on more detailed infor­ma­tion about one’s eyes in order to pro­gram the excimer laser more accu­rate­ly and thus allow for the most ide­al eye reshap­ing pro­ce­dure.

What Makes CustomVue LASIK More Superior?

As men­tioned, the wave­front tech­nol­o­gy used for the Cus­tomVue LASIK makes this par­tic­u­lar pro­ce­dure more detailed and effec­tive for the indi­vid­ual needs of the patient.

CustomVue LASIK Is More Precise

If you wear glass­es, you’re famil­iar with the pro­ce­dure of get­ting your eye­glass­es pre­scrip­tion. The doc­tor typ­i­cal­ly shifts between dif­fer­ent lens­es and ask about the vision clar­i­ty with each lens. In the end, you often have to choose between two lens­es. How­ev­er, some­times it’s chal­leng­ing to deter­mine which lens suits you bet­ter. In order to deter­mine the ide­al pre­scrip­tion for you, your doc­tor has to change between 0.25 diopter (D), which is the small­est mea­sure­ment unit for glass­es. This is why your pre­scrip­tion will always say some­thing like ‑2.25 D or ‑2.5 D, but you’ll nev­er see a num­ber like ‑2.3 D or ‑2.4 D.

The wave­front tech­nol­o­gy of Cus­tomVue LASIK allows the mea­sure­ments in even small­er units, which is 0.01 D. That way, the com­put­er can auto­mat­i­cal­ly cal­cu­late the ide­al pre­scrip­tion for you, down to the small­est unit, mak­ing it per­fect­ly tai­lored to your eyes. The dif­fer­ence in num­bers is clear – Cus­tomVue LASIK mea­sures the vision 25 times more pre­cise­ly than the reg­u­lar lens units.

CustomVue LASIK Is More Specific

Essen­tial­ly, deter­min­ing eye­glass­es pre­scrip­tion dur­ing the exam assess­es the eye’s abil­i­ty to focus light as a whole. There­fore, just one lens is used to cor­rect the vision of the entire eye.

On the oth­er hand, cus­tom wave­front LASIK gath­ers infor­ma­tion about the eye’s abil­i­ty to focus light from hun­dreds of ref­er­ence points on the eye. Thanks to that prac­tice, it’s pos­si­ble to cre­ate a rather detailed map of the refrac­tive error. It’s this map that’s then used to pro­gram the excimer laser for a more spe­cif­ic and per­son­al­ized vision cor­rec­tion.

Different Types of Custom LASIK

We can dif­fer­en­ti­ate three basic types of cus­tom LASIK pro­ce­dure:

Wavefront-guided LASIK

Wave­front-gen­er­at­ed mea­sure­ments are used to deter­mine exact­ly the way light trav­els through the patient’s eyes and falls on the reti­na. This pro­ce­dure can cor­rect near­sight­ed­ness, far­sight­ed­ness, and astig­ma­tism as well as reduce irreg­u­lar high­er-order aber­ra­tions to fur­ther improve the clar­i­ty of vision post major refrac­tive cor­rec­tions.

Wavefront-optimized LASIK

This par­tic­u­lar wave­front-gen­er­at­ed pro­ce­dure focus­es on the eye’s front sur­face cur­va­ture, which then allows for the preser­va­tion of the cornea’s nat­ur­al aspher­ic shape. This min­i­mizes the risk of spher­i­cal aber­ra­tion.

Topography-guided LASIK

This pro­ce­dure eval­u­ates the sur­face of the eye to deter­mine refrac­tive errors togeth­er with oth­er vision prob­lems caused by corneal irreg­u­lar­i­ties. This is not a wave­front-gen­er­at­ed pro­ce­dure per se, but it still offers a more detailed and per­son­al­ized cor­rec­tion com­pared to con­ven­tion­al LASIK.

The CustomVue LASIK Procedure

The entire LASIK pro­ce­dure typ­i­cal­ly takes between 10 and 15 min­utes for both eyes. Once com­plet­ed, the patients can usu­al­ly leave after about an hour. Before they start the pro­ce­dure, the sur­geon numbs the eye with anes­thet­ic drops. Then they use the Cus­tomVue sys­tem for guid­ance dur­ing the pro­ce­dure. In most cas­es, patients don’t feel any dis­com­fort dur­ing the pro­ce­dure.

After a CustomVue LASIK Procedure

Once they’re free to leave after hav­ing the LASIK cor­rec­tion pro­ce­dure done, patients should head home and get some rest for a cou­ple of hours. Some dis­com­fort or slight pain might occur dur­ing those hours, and tak­ing pain reliev­ers in this case is per­fect­ly fine. Typ­i­cal­ly, there’s no issue what­so­ev­er when it comes to resum­ing reg­u­lar dai­ly activ­i­ties after just a day or two.

Ideal Candidates for CustomVue LASIK

In order to deter­mine whether a patient is a good can­di­date for Cus­tomVue LASIK, one must go through a thor­ough eye exam­i­na­tion. What’s more, it’s nec­es­sary that patients who want to cor­rect their near­sight­ed­ness are at least 18 years old. This is due to the fact that the eyes have to be mature enough for the pro­ce­dure. There shouldn’t be any infec­tion or eye injury at least a whole year before the pro­ce­dure.

There are also patients who are sim­ply not eli­gi­ble for Cus­tomVue LASIK due to their cur­rent con­di­tions or health issues. These include patients who are:

  • Preg­nant or nurs­ing
  • Suf­fer­ing from a degen­er­a­tive or autoim­mune dis­or­der
  • Suf­fer­ing from a con­di­tion that affects the heal­ing process

Potential Risks and Complications

Cus­tom wave­front LASIK is known to be rather safe and effec­tive as a vision cor­rec­tion pro­ce­dure. How­ev­er, this is a surgery, and as such, it’s impos­si­ble to claim that it’s 100% free from com­pli­ca­tions and risks. In rare cas­es, some patients could expe­ri­ence cer­tain side effects, such as infec­tions or improp­er cor­rec­tions. To avoid this from hap­pen­ing, make sure to choose a renowned and expe­ri­enced sur­geon for the job.

Benefits of Custom LASIK Procedure

As it’s gen­er­al­ly con­sid­ered a low-risk pro­ce­dure that offers great pre­ci­sion and results, cus­tom wave­front LASIK surgery has become the go-to solu­tion for peo­ple who wish to cor­rect their vision. It’s also high­ly rec­om­mend­ed by lead­ing LASIK sur­geons and oph­thalmic spe­cial­ists across the globe. This pro­ce­dure is com­plete­ly blade-free, which makes it a min­i­mal­ly inva­sive surgery that offers incred­i­ble pre­ci­sion. The laser’s ultra­vi­o­let light is pro­grammed to remove a small part of corneal tis­sue with­out dam­ag­ing the sur­round­ing eye. It’s also impor­tant to men­tion the con­ve­nience of short down­time and the fact that there’s no need for pupil dila­tion.
