LASIK / IntraLASIK

IntraLASIK - Safer and Better Vision

Centre for Sight introduced IntraLASIK to the UK in 2004. IntraLASIK laser eye surgery is the safest, most precise vision correction option with the longest track record available in the world today!

  • LASIK involves creation of a micro-thin flap of the cornea. The flap is lifted and a laser is used to reshape the cornea.
  • Traditional LASIK uses a blade to create the flap. Intralase LASIK or IntraLASIK uses a precise Laser to create the flap with computer controlled precision and accuracy.
  • IntraLASIK is much safer with precision flaps and no blade related complications
  • Wider range of correction possible
  • Shortsight upto -12.00 diopters (in special cases)
  • Longsight upto +5.00 diopters (even more in special circumstances)
  • Astigmatism upto 5 diopters - possibly more using Centre for Sight designed software
  • Presbyopia - need for reading glasses can be corrected using Supracor LASIK

IntraLASIK - the procedure:

Step 1: You are given a sedative to help you relax. Strong anaesthetic drops numb your eyes beforehand. Antibiotic drops are used to prevent infection.

Step 2: The IntraLase Femtosecond Laser is used to create thousands of tiny bubbles to precisely separate a corneal flap at a specified depth in the cornea.

Step 3: The flap is then carefully lifted.

Step 4: The Bausch + Lomb-Technolas Excimer Laser is used to reshape the inner cornea, customised to each individual eye from preoperative tests including wavefront evaluation and topography.

Iris recognition technology fixes and tracks alignment of the laser in multiple dimensions. This ensures delivery is absolutely precise and you do not have to worry if your eyes move! (The technology has the added benefit of confirming the correct treatment is being applied to the correct eye!)

Step 5: When the treatment is complete the flap is replaced and allowed to dry. The flap attaches without the need for stiches and more eye drops are administered to prevent infection and avoid discomfort.

All patients at Centre for Sight undergo IntraLASIK - No compromise

In traditional LASIK surgery, a mechanical microkeratome with a surgical blade is used by the surgeon to cut a tiny-hinged flap of tissue. Since its introduction in 1989, the design of the microkeratome has seen very little advancement. Centre for Sight surgeons previously performed thousands of LASIK treatments with this traditional method, but keeping to its ethos of safety first, in 2004 blade keratomes were abandoned in favor of the safer option - IntraLASE. It took two years before other providers followed the Centre for Sight lead and acquired the technology.

To eliminate complications attributed to the blade microkeratome, ALL patients undergoing LASIK at Centre for Sight are under going IntraLASIK – no compromise! Some centres will "upsell" use of Intralase over the microkeratome. Our philosophy is to ensure patients get the absolute best - so why offer a technique that is in any way deficient?

IntraLASIK is derived from the laser IntraLASE, a femtosecond laser first commercially available for creating corneal flaps for Lasik in 2002 (USA) and 2004 (Europe). Centre for Sight acquired the first laser in the UK in 2004 and was amongst the first 10 in Europe.

Advantages IntraLASIK

"Flaps heal more strongly and quickly"

  • The IntraLase iFS eliminates all blade related complications attributed to the mechanical blade keratome.
  • Computer controlled accuracy of the IntraLase iFS creates a precise cornea resection withgreater consistency of flap thickness. If you were not a candidate for traditional LASIK, you may still be a candidate for the IntraLASIK procedure.
  • The long wavelength of the IntraLase iFS laser creates precision flaps without heating or damaging surrounding tissue.

"IntraLASIK results in less symptoms of dry eye"

  • The precision shape of the flap allows it to settle back with a tighter seal.
  • IntraLASIK flaps heal more strongly and quickly.
  • IntraLASIK flaps result in less symptoms of dry eye.

Pre-op LASIK and IntraLASIK Consultation

A successful LASIK procedure begins with a thorough patient consultation with numerous supporting investigations. As this is considered so important, all consultations at Centre for Sight are performed by a Fellowship trained consultant – no compromise.

During consultation, general information will be gathered about your eyes. Information will also be sought about your lifestyle: your history of glasses and contact lens wear, physical activities you participate in, your visual needs and how you expect your life to change after the LASIK procedure.

"All our consultations are performed by a surgeon, no compromise!"

The results of your consultation will be discussed with you and you will have the opportunity to have any questions answered by one of our fellowship-trained consultants. Your suitability for IntraLASIK / LASIK and alternative vision corrective treatments suitable for you will be discussed.

Your tests

Your consultation with us is arguably the most comprehensive eye examination you will ever have. It does take a while to be thorough so we suggest you allow 2-3 hours for its completion. To confirm the exact refractive error in your eyes and determine the best available treatment specifically for you, our Fellowship-trained consultants and technicians will examine and perform tests on your eyes:

  1. Your eyes will be refracted initially to check what power your eyes require for full and perfect correction.
  2. Corneal topography equipment is used to map out the surface of your eyes. The corneal topography equipment measures the contour of your cornea in 3 Dimensions. Further OCT scanning may be required depending on preliminary findings. OCT scanning is used to measure the distribution of your corneal epithelium. It is also used to check your optic nerve and macula.
  3. Wavefront Aberrometry will also be performed to determine if you have any high-order aberrations that might be affecting visual quality and any night vision troubles.
  4. Corneal pachymetry measures the thickness of the cornea.
  5. The Ocular Response Analyser (ORA) is used to determine the elasticity of your cornea prior to laser eye surgery.
  6. Dry eye tests are also performed. Should there be any significant findings, specific treatment will be suggested prior to your procedure.
  7. Your eyes will be dilated to check the back of your eye, as a result you will not be able to drive after your consultation.
  8. Additional tests may be required depending on findings at consultation.

This information is valuable in performing the IntraLASIK / LASIK procedure and is used by your consultant to determine the best treatment option available for each individual eye.

The LASIK and IntraLASIK Procedure

Prior to each procedure, "pre-flight" checks are performed by the surgeons and technicians well before the first patient arrives. To ensure consistently phenomenal outcomes, Centre for Sight standards far exceed the minimum requirement. For instance although not necessary, the laser is calibrated immediately prior to each patient treatment.

On the day of your surgery, dress comfortably and avoid any clothes that are tight fitting or shed fibres.

IntraLASIK Step by Step:

  • You are given a mild oral sedative to help you relax and make you less anxious. After your eye has been numbed with anaesthetic eye drops, the Consultant gently places an eyelid clip to hold your eyelids open. You will remain awake and comfortable throughout the procedure.
  • Your surgeon will then begin the first step of any LASIK procedure by creating a corneal flap. The IntraLase FS laser is to create the flaps in both eyes.
  • The laser bed will be rotated to the Excimer laser. IRIS recgonition is performed to recognize and track the eye.
  • The flap will be gently lifted from the centre of the cornea to allow the excimer laser access to the underlying tissue.
  • To begin the second step of the IntraLASIK procedure, your surgeon will ask you to look at a target flashing red light. The cool light of the excimer laser will reshape the corneal tissue, correcting your vision as you look at this light. You will hear clicking sounds as a microscopic layer of tissue is vaporized and the iris recognition and registration eye tracker ensures accurate placement of each laser pulse. This process will last from a few seconds to a minute, depending on the amount of correction necessary.
  • When the procedure is complete, your surgeon will meticulously replace the corneal flap and gently smooth it into place.
  • You will then recover in a reclining chair for 15 to 20 minutes and then your vision will be checked. Your eye surgeon will check your eyes to make sure all is well before you go home.
  • You will be given eye drops, and instructed in their use.

Directly after surgery:

  • You may notice that your vision will be a little blurry immediately following your LASIK /IntraLASIK procedure. This blurriness will gradually clear in the next few hours. You might even get the sensation that you have soap in your eyes for a couple of hours.
  • Someone will need to drive you home and we suggest you go to sleep for the next 4 hours after putting in the first dose of your eye drops.
  • After 4 hours, you may watch TV or read as long as you take your eye drops as well as lubricant drops frequently every five to ten minutes.
  • It is important to avoid wind or any type of air turbulence that would cause your eyes to dry out.

Follow up care for LASIK or IntraLASIK

Follow up care is vital for good outcomes and we at Centre for Sight like to see our patients ideally the following day or at least within a few days of the procedure. Our staff will call you the night of the procedure and then next day if you are unable to attend for follow up.

  • You will be provided with eye drops and protective eyewear. Please follow the instructions provided.
  • By the first post-op visit, most patients are able to drive themselves to their appointment. Most patients are excited about their vision the following day and most see 20/25 (6/7.5) or better.
  • Following LASIK, your vision improves very rapidly, allowing you to return to work within a day or two after you have had the procedure.

Activities following LASIK / IntraLASIK

SHOWERING - NEXT DAY - with eyes closed

DRIVING - When you feel comfortable with your vision and are able to meet the visual requirement for driving (number plate at 25 yards). The majority of patients are able to accomplish this the next day.

FLYING - SAME DAY of the procedure. You may need artificial tears if taking a long-haul flight.

EXERCISE - Moderate Right away - Heavy after 10 Days

SWIMMING - 4 weeks

DIVING - 6 weeks

EYE MAKE-UP
Mascara 4 weeks - the wand can accidentally hit your corneal flap which will not be felt as the surface will be a little numb. Consider eyelash tinting before the procedure.
Other 2 days - taking care to remove gently without much pressure on the eye
