LASER EYE TREATMENT – LASIK, Femto LASIK, SMILE®, LASIK for Presbyopia

Laser eye surgery procedures for elimination of glasses or eye number includes surgical procedures like FEMTO – LASIK, LASIK, SMILE, PRK, Topoguided PRK etc which are effectively used to remove dependence on glasses.
A. FEMTO LASIK
Also called as “Bladeless LASIK” involves use of two different kinds of laser. First, Femto second Laser is used to create the flap, instead of a blade and then Excimer laser is used to reshape the cornea in order to remove the glass number. The flap is then put in place. The procedure is performed under anaesthetic drops and both eyes are treated at the same sitting.
B. LASIK
involves using a Microkeratome to create a hinged flap on the cornea followed by application of laser rays on the corneal bed to remodel the cornea and replacing the flap. The procedure is performed under anaesthetic drops and both eyes are treated at the same sitting.
C. SMILE®
Small Incision Lenticule Excision (SMILE) involves use of Femto second laser to remove a thin layer of corneal tissue from within a pocket created within the cornea. Useful for thin corneas where LASIK or FEMTO LASIK are not permissible. No blades are used here. The procedure is performed under anaesthetic drops and both eyes are treated at the same sitting. Postoperative recovery is much faster.
D. PRK
involves using laser to remodel the cornea without using the Microkeratome. Useful for thin corneas where LASIK or FEMTO LASIK are not permissible. PRK can also be done, Topo guided in irregular corneas
E. Presbyopic LASIK
LASIK performed to treat patients with presbyopia along with other refractive errors. It involves meticulous planning but can give excellent results and make patients very happy.

FREQUENTLY ASKED QUESTIONS
Q1. Who can undergo LASIK?
Adults > 18years of age No other eye disease Adequate corneal thickness Normal cornea
Q2. How safe is LASIK?
LASIK is a very safe and universally accepted procedure. As of 2011, 11 million LASIK procedures have been performed in the USA and as of 2009, 28million LASIK procedures have been done worldwide. (Data source – Wikipedia)
Q3. What are the risks of LASIK surgery?
  • 1. Vision loss due to Infection following LASIK is extremely rare. Some reports claim this to be 1 in 10,000 as compared to 1 in 2000 in daily contact lens wearer. Proper hygiene and sterility in the LASIK suite can help bring down the risks to the minimum.
  • 2. Induction of Higher order aberrations – This was much common earlier but nowadays has been effectively taken care of with the help of Wavefront guided treatment. Wavefront analysis or Aberrrometry is done as part of LASIK screening and patients who need to undergo wavefront guided treatment are accordingly advised and treated to avoid higher order aberrations, after the surgery.
  • 3. Dry eyes – Post LASIK dry eye can be a temporary problem with some patients. However, effective screening for Dry Eyes are done at Eye Life™ prior to rule out any preexisting Dry eye in patients.
  • 4. LASIK flap related complications – Flap related complications are much less in today’s scenario due to the availability of good quality microkeratomes and blades. Also, at Eye Life™ we now offer the option of “Bladeless LASIK” who want it.
Q4. Are both eyes treated on the same day?
Yes, all laser procedures are performed on both eyes on the same day.
Q5. I am a contact lens wearer – can I undergo Laser eye surgery?
Yes, you surely can. However, you do need to stop wearing Contact lens for a week before undergoing and Laser eye procedure. This is because contact lenses may induce some change in the corneal shape following long standing wear.
Q6. I have very high glass number. Till how much number can be corrected with Laser surgery?
LASIK surgery can correct upto -8 diopters or more, based on corneal thickness. In case the corneal thickness is inadequate, newer and more advanced techniques like SMILE or Surface ablation(PRK) can be done. For higher numbers or thinner corneas, ICL ( Implantable Collamer Lens) can be implanted with excellent results.
Q6. What is ICL?
ICL or Implantable Collamer Lens are special lenses that are implanted inside the eye so that the patient does not have to wear glasses. Proper measurement of the lens size is done and the lens implanted inside the eye, behind the iris and in front of the natural lens. The advantages of the lens include – ability to correct very high numbers and it is a completely reversible procedure because the lens can be removed from the eye whenever required. This procedure is performed one eye at a time, usually at the interval of one week.
Q7. What are the complications of ICL?
ICL is a very safe procedure. Complications like cataract, glaucoma, etc can rarely happen. However, ICL implantation being a reversible procedure, the lens can be removed whenever required.
Also, unlike laser eye surgery, ICL is an intraocular procedure i.e. we have to cut open the eye to implant the lens and therefore carries risks associated with any intraocular surgery.
Q8. What isFemto LASIK / Bladeless LASIK? What are its advantages over LASIK?
In Femto LASIK, we employ another additional laser called as Femtosecond Laser to cut the cornea and create the flap which was earlier created with a microkeratome and blade in LASIK. Then, the laser treatment is done using excimer laser as in LASIK. Femto LASIK is thus called “Bladeless LASIK.” This procedure helps in avoiding all complications that can arise due to the microkeratome and blade.
Q9. What is SMILE®?
SMILE® or Small Incision Lenticule Extraction is an advanced procedure in which Femtosecond laser is used to remove a small sliver of corneal tissue so as to enable correction of refractive error. Excimer laser is not used at all. SMILE® helps in quicker postoperative recovery and less postoperative pain.
Q10. What are the different types of lasers that are used for laser eye surgery?
The two different types of laser used for removal of glass number –
  • 1. Excimer laser - Photoablative laser, which can make very fine ablation on the corneal tissue and has been used for more than two decades now for the correction of glass number.
  • 2. Femtosecond laser – This is photodisruptive laser which works by disruption of corneal tissue. It was initially made to create flaps so as to help avoid use of microkeratome but with the advent of SMILE® the entire refractive error can be corrected by SMILE®.
Q11. How much time will the laser eye surgery take and how early can I resume my studies/work?
LASIK / Femto LASIK / SMILE® take few minutes to perform. Postoperative checkup is required the very next day. Soon after, you can resume your normal work or studies.
Q12. What tests are done prior to a LASIK procedure? How long does it take?
About 12 odd tests are done prior to LASIK to determine suitability to undergo LASIK. These include, Scheimpflug topography, Pachymetry, Pupillometry, dry eye tests, cycloplegic refraction, aberrometryetc to name a few. These tests take about 2 hours to complete.
In case you want to get your LASIK screening test done faster, ask for a - Laser Fast LASIK Screening.

LASER EYE TREATMENT FOR RETINA


At Eye Life, our Retina Specialist, Dr Gaurav Shah performs eye lasers for various retinal diseases. We use a 532nm wave length eye laser for retinal diseases like diabetic retinopathy, central retinal vein occlusion, diabetic macular edema, central serous chorioretinopathy etc. Retinal laser can be done as an outdoor procedure in the sitting position and does not require injection before or eye patch after the procedure. Retinal laser needs only prior dilatation of the pupil. Unlike surgery, it does not have any restrictions after the procedure and patients can resume normal activities on the same day itself.
