Clear Lens Extraction (CLE)/Refractive Lens Exchange (RLE) Surgery in Delhi

Clear Lens Extraction (CLE) or Refractive Lens Exchange surgery is meant for people who are not qualified or ideal candidate for LASIK laser eye surgery. It is a vision correction surgical procedure intended to reduce or eliminate the need for glasses or contacts for people over the age of 40. CLE may be a better option for someone considering LASIK over the age of 40 years old.

Though CLE is very similar to cataract surgery, it has multiple benefits that extend well beyond. Hitech eye centre in Delhi, India is among the best eye hospitals to conduct Clear Lens Extraction (CLE)- lens replacement surgery at all its centres at affordable cost.

Refractive Corrections offered with CLE

  • High Myopia – Nearsightedness or short sightednes
  • High Hyperopia – Long sightedness or farsightedness
  • High Astigmatism

Advantages of CLE and RLRlense

CLE-Lens replacement surgery involves replacing the eyes’ natural lens with an artificial lens so that the vision is improved or the existing spectacle power is corrected.

Refractive lens replacement surgery which is based on Cataract Surgery is performed in the similar manner. But it is called clear lens extraction/refractive lens exchange, due to the reason that the eye’s natural lens is not cloudy as yet from cataract when it is removed and replaced. In CLE a non-cloudy natural lens is removed and replaced with an artificial one. This artificial lens carries the power to be corrected.

The advantage of CLE is that once you have had the lens replacement surgery you will never require Cataract Surgery because the natural lens of the eye has already been replaced.

Lens replacement surgery is also termed RLR (Refractive Lens Replacement) and RLE (Refractive Lens Exchange). If you are presbyopic (require glasses to do near work also), by exchanging your own natural lens for a multi-focal lens / accommodative lens (crystalens) implant, both eyes can regain their ability to focus at all distances. This surgery is also known as PRELEX (Presbyopic Lens Exchange).

Types of Lens Replacement (CLE)

As in cataract surgery, three types of IOLs are available to replace your natural lens, depending on your vision needs and the health of your eyes. They are:

Fixed Focus Implant / Monofocal Implantfocus-implant

This type of lens implant is most often indicated if you are over 40 years of age. However, reading glasses would still be required with this type of surgery. If you already suffer from cataract, then lens replacement may be a good option, as the natural lens may need to be replaced over time, anyways

Multi Focus Implant
This type of lens implant known as PRELEX (Presbyopic Lens Exchange), can improve near and distant vision, hence its suitable if you are both hyperopic and presbyopic. PRELEX replaces the natural lens with a multi-focal intra-ocular lens implant which eliminates the need for glasses or contact lenses, completely.


Accommodative Lens Implantaccomodative-implant

This lens implant can artificially accommodate itself like the eye’s natural lens instead of remaining rigid like other types of lens replacements. The lens works naturally with your eye muscles using hinges, which are designed to allow the lens to move and focus on objects at all distances.
