Removal of Spectacle/Glasses

If you ever wanted to get rid of spectacles, then this article should interest you. I have authored it in Q & A form to answer usual queries on this topic. Lets first understand why do we need spectacles or contact lens. Various parts of our eye allow the image to focus on retina for us to see clearly. If they do not do so in case of refractive error , we see blurred objects.

A refractive error is a condition in which a clear image fails to focus on the retina due to variations in optics of eye (cornea, lens or length of the eyeball). The variations are determined by our genetic/chromosome pattern like any other organ of the body.

There are three different types of refractive errors namely, myopia, hypermetropia and astigmatism.

  • Myopia or short-sightedness is a condition wherein the image is focussed in front of the retina. The person is unable to see distant objects clearly.
  • Hypermetropia or far-sightedness is a condition when the image get focussed behind the retina. The person is unable to see near objects clearly.
  • Astigmatism or cylindrical error is the condition when due to irregular curvature of the cornea, a point focus of image is not formed at the retina. objects at most distances appear blurred to such people. It can be of simple, compound and mixed type depending on where and how the image is formed in relation to retina.

Refractive errors occur due to a combination of genetic and environmental factors.

Refractive errors can be overcome by either using temporary aids like glasses / contact lenses or removed permanently by undergoing a refractive surgical procedure-LASIK/PRK/SMILE/Phakic ICL/RLE.

The option of any of above depends on the age, refractive error ,eye condition and PERSONAL CHOICE.

  • Age Criteria- contact lens and LASIK is not an option for children. They should wear spectacles as they are safe and maintenance free. As the child grows older and is able to handle contact lens say around 14 or 15 years of age, they can star wearing soft contact lens .The option of LASIK is after 18yrs age as the refractive error becomes stable by this time.
  • If contact lens do not suit you or cumbersome to handle, LASIK/PRK is a good option .It is a safe day care procedure and gives long lasting solution. .There are certain parameters in eye which need to be examined upon prior to opting for LASIK eg-corneal thickness, curvature, tear film, retina etc. The ophthalmologist will examine your eyes in detail and guide you accordingly.

The choice of refractive procedure is based on the power of glasses, eye parameters and age of patient. There is a strict selection criteria for each procedure and we examine your eyes thoroughly before deciding on same. We examine your eyes in detail to decide what option would be best for your eyes. Broad guideline to help you understand the refractive options for various spectacles power:

  • -1 to -8 myopia (normal cornea):Lasik standard/ customized or wavefront guided .If the cornea thickness is adequate, we can sometimes correct upto -10 also but prefer phakic ICL for high numbers) .(for detailed info: Click Here)
  • -1 to-8 (borderline thin cornea): Ultra Thin Flap Lasik/ PRK-Surface Ablation/ Epi Lasik
  • +2 to +6 hyperopia (normal cornea) : Lasik
  • 1 to 6 astigmatism- Lasik
  • -8 to -20 (any type of cornea): Phakic ICL-Implantable Collamer Lens-Phakic Intraocular Lens (for detailed info: Click Here)
  • -20 to-30 pathological myopia / +10 or more hyperopia (age >40yrs)/ : CLE-Clear Lens Extraction/Refractive Lens Exchange
  • Presbyopia (near vision problem in elderly) : Supracor Presbyopic LASIK (for detailed info: Click Here ) Monovision Lasik

All refractive procedures are walkin -walk out day care procedures. One is expected to rest for a day and can resume routine work from next day. Majority of refractive error is restored soon after while the fine vision may take few days to settle. One can safely resume work in few days.

There is a strict selection criteria for each procedure and we examine your eyes thoroughly before deciding on same. Once the eyes are decided to be suitable for a certain procedure, its very safe. Few incidence of complications (like any surgical procedure) can be managed well.
