Blade vs Bladeless LASIK Surgery

If you’re think­ing about LASIK, you might not have known it can be done with and with­out a sur­gi­cal blade.

LASIK (an acronym for Laser Assist­ed In Situ Ker­atomileu­sis) was first used in the U.S. in 1991 and has been updat­ed pret­ty reg­u­lar­ly with new laser tech­nolo­gies. The pro­ce­dure com­mon­ly mar­ket­ed as blade­less LASIK came in 2007, intro­duced as IntraLase.

Isn’t All LASIK Bladeless LASIK?

New­er LASIK pro­ce­dures are blade­less, although some eye sur­geons bris­tle at the term “blade­less” since all LASIK pro­ce­dures cut into the eye sur­face. The ear­li­est pro­ce­dure, which is still safe­ly per­formed today with very few com­pli­ca­tions, uses a spe­cial­ized blade.

First, a lit­tle back­ground. Myopia (near­sight­ed­ness) and far­sight­ed­ness hap­pen when var­i­ous parts of the eye change shape and inter­fere with prop­er vision. In near­sight­ed­ness, the eye­ball becomes elon­gat­ed, dis­rupt­ing the way the cornea or lens fit on it. Or some­times they curve on their own and dis­rupt the con­for­mi­ty. These changes are often genet­ic and begin to appear in young adult­hood.

Far­sight­ed­ness (hyper­opia) occurs when the eye­ball is too short and the eye focus­es on images behind the reti­na instead of on it. It can dis­rupt vision at any dis­tance. All LASIK pro­ce­dures fix these prob­lems by reshap­ing the eye, which involves cut­ting into the sur­face to cre­ate a very thin flap.

Tra­di­tion­al LASIK cre­ates the flap with a sur­gi­cal blade called a micro­ker­atome. The new­er LASIK pro­ce­dures approved since 1999 use dif­fer­ent types of lasers to cut into the eye, cre­at­ing the “LASIK flap.”

That’s essen­tial­ly the dif­fer­ence in all LASIK surgery pro­ce­dures. After the flap is cre­at­ed, the sur­geon lifts it and directs a laser under­neath it to lit­er­al­ly reshape the eye to cor­rect the vision. The flap is put back down and allowed to heal, which takes a week or less.

Is Bladeless LASIK Eye Surgery Safest for Patients?

Because each patient’s eyes are dif­fer­ent, it’s best to go with the surgeon’s opin­ion when it comes to decid­ing which kind of LASIK surgery to have. Many sur­geons use dif­fer­ent tech­niques, tak­ing into con­sid­er­a­tion com­pli­ca­tions like glau­co­ma and pre­vi­ous eye surg­eries.

As for safe­ty, the real fac­tor is the surgeon’s skill but over­all LASIK is among the safest surg­eries. Both laser and micro­ker­atome cut­ting car­ry cer­tain risks and ben­e­fits.

Microkeratome — Blade vs Bladeless  LASIK:

Microkeratome-created flaps:

  • Very low risk for detached flaps and oth­er com­pli­ca­tions
  • Pos­si­ble high­er risks for “but­ton­holes” in flaps
  • High­er risk for vari­a­tion in flap thick­ness
  • Bet­ter for patients with glau­co­ma
  • Bet­ter for repair­ing pre­vi­ous LASIK errors
  • Takes less time to per­form
  • Requires less suc­tion, which can be painful for patients

Laser-created flaps:

  • Increased risk for ede­ma (swelling) on the flap that can length­en recov­ery time
  • Low­est risk for flap com­pli­ca­tions
  • No vari­a­tion in flap thick­ness
  • Tem­po­rary light sen­si­tiv­i­ty
  • More expen­sive
  • Bet­ter post-surgery vision
  • Rarely requires sub­se­quent “touch up” surgery

Is Bladeless Lasik Less Painful Than Traditional LASIK?

Hon­est­ly, LASIK surgery is pret­ty low on the pain scale, espe­cial­ly com­pared to oth­er surg­eries you may have had, such as appen­dec­to­my or chole­cys­tec­to­my (gall­blad­der removal).

Your sur­geon will numb your eyes with drops, and there is lit­tle actu­al pain after the pro­ce­dure. Many patients feel like there’s some­thing float­ing around in their eyes, and tear­ing is pret­ty com­mon. There may be a lit­tle bit of burn­ing or itch­ing while the cornea heals, but noth­ing approach­ing actu­al pain.

Per­fect, or near-per­fect eye­sight is a gift. If you have pret­ty bad eye­sight and are tired of wear­ing glass­es or con­tact lens­es, you should con­sid­er LASIK. Con­tact us for a free con­sul­ta­tion, today!
