If you need glasses or contact lenses to see better then you are amongst 40% of the world's population who have Refractive errors. Refractive surgery has been a life changer for those who are dependent on spectacles. LASIK laser for removal of glasses has been the most successful and widely performed procedure globally. At Vision Plus Eye Centre our Doctors have a wide experience of the latest techniques for spectacle removal. With their expertise we will help you understand the cutting edge technologies available and which is best suited to your eyes. After all, when it is something as precious as your sight, you want safety, reliability and accuracy. With Vision Plus Eye Centre’s personalised Vision Correction, you are assured of the best.
Am I a suitable candidate for Refractive surgery??
Above 18 years of age
Refraction stable for at least 1 year
Healthy eyes
Not pregnant or nursing
Not suffering from Autoimmune disease or diabetes
What are the latest techniques for Spectacle removal?
How do I know which procedure for spectacle removal is best for me?
The choice of technique for spectacle removal depends on several factors. Our team at Vision Plus Eye Centre does an in depth evaluation of your eye, and only after considering all the parameters, and discussing the relative pros, cons and estimated cost, do we suggest the best technique suited for your eyes.
1. Type of Refractive error- Myopia, Hypermetropia, Astigmatism, Presbyopia
2. Magnitude of spectacle power- Low, moderate or high
3. Pachymetry- Thickness of the cornea
4. Keratometry- Steepness of the cornea
5. Topography- 3 dimensional shape of the cornea
6. Aberration Profile of the eye
7. ACD- Anterior chamber depth
8. Pupillometry-Pupil size in bright and low light conditions
9. Dry eye evaluation
PRK/Advanced Surface Ablation
Photorefractive Keratectomy (PRK) was the first Excimer laser based technique developed in the 1990s for correction of Refractive errors like Myopia, Hypermetropia and Astigmatism. Over the years it has evolved and with newer machines is once again back in vogue. It basically involves removing the top 50um layer (Epithelium) and using the Excimer laser to reshape the cornea using sophisticated nomograms. The main advantage being it is Flapless & conserves corneal tissue. Hence it is indicated in patients with thin corneas or who may have some abnormal topography. Also those active in contact sports or in the military will benefit from a flapless procedure. Drawback is the longer healing time and initial postoperative discomfort as the epithelium is removed and a bandage contact lens has to be used for a few days.
LASIK (Laser assisted in situ Keratomileusis)
This is the time tested procedure for removal of spectacles. A thin flap is made in the cornea which is everted and Excimer laser rays are focussed to reshape the cornea according to a customised pattern. It is painless and vision recovery occurs rapidly.
An automated blade is used to make the flap after stabilising the eye with a suction ring. The flap thickness can vary from 100- 180um and is cost effective since only one laser is used.

SMILE (Small Incision Lenticule Extraction)
This is a femtolaser based technique in which a thin slice of cornea is cut with the laser and then manually extracted through a small incision. The thickness of the tissue removed depends on the refractive power (spectacle number). The advantage is that it’s flapless and probably causes less postoperative dryness. However, recovery is slower than Lasik and it has its limitations in the correction of cylinder and lower powers. Being a relatively new technique it is still undergoing standardisation and is not easy to retreat if there is residual power.
PHAKIC IOL / Implantable Contact Lens
Not all patients are suitable for cornea based refractive laser surgery due to thin corneas or extreme myopia / astigmatism. The latest technology for glasses removal is placing a special contact lens within the eye called ICL or Phakic IOL. The lens is customised according to the patient's eye dimensions and power. For this we do certain additional tests like Optical Biometry and White to white measurements.
At Vision Plus Eye Centre we do a detailed preoperative examination and specialised tests to customise the Phakic IOL to suit your eye. Usually, one eye is operated at a time. On the day of surgery you will need to dilate your eyes and have a head wash. After anaesthetising your eye with drops, a small 2.8mm incision is made and the lens is injected into the desired position. The surgery is painless and takes about 15 min. You can quickly resume normal daily activity with a few precautions.

REFRACTIVE LENS EXCHANGE (RLE)
In some cases both Lasik and Phakic IOL may not be suitable due to the high power and shape of the eye. Still, we can have freedom from glasses by removing the natural lens and replacing it with a Multifocal or Monofocal artificial intraocular lens. Patients above the age of 40 years who want to get rid of specs can opt for RLE.
