Nandadeep Refractive Surgery center is one if it's kind in Southern Maharashtra. Experienced surgeon, world class operation theatre, latest technologies & equipments, pre-surgery extensive assessment are the key points for consistent & great surgical outcomes.

Refractive Surgery, also known as Vision Correction and Laser Eye Surgery refers to surgical procedure used to correct vision problems. Most types of vision correction surgery change the shape of cornea (corneal reshaping) while other procedures involve implanting a lens inside eye.

What are refractive errors?

refractive errors
  • Myopia - For people who are nearsighted, certain refractive surgery techniques will reduce the curvature of a cornea that is too steep so that the eye's focusing power is lessened. Images that are focused in front of the retina, due to a longer eye or steep corneal curve, are pushed closer to or directly onto the retina following surgery.
  • Hyperopia - Farsighted people will have refractive surgery procedures that achieve a steeper cornea to increase the eye's focusing power. Images that are focused beyond the retina, due to a short eye or flat cornea, will be pulled closer to or directly onto the retina after surgery.
  • Astigmatism - Astigmatism can be corrected with refractive surgery techniques that selectively reshape portions of an irregular cornea to make it smooth and symmetrical. The result is that images focus clearly on the retina rather than being distorted due to light scattering through an irregularly shaped cornea.

Different types of refractive surgeries available at Nandadeep:

Photorefractive Keratectomy (PRK)
  • PRK is the first generation laser procedure to improve vision and reduce or eliminate the need for eye glasses or contact lenses.PRK is characterized by surface ablation surgery, where the epithelial layer of cornea is ablated to allow the excimer laser to correct cornea. Once the visual defect is corrected, a protective lens is placed over the eye until epithelium grows back within a few hours. Although there are other well established laser vision correction techniques, PRK is still well accepted
  • Visual recovery following PRK treatment generally takes longer than with other procedures and can be accompanied by some discomfort for first 2-3 days
  • At Nandadeep, we use the most efficient and robust excimer laser in the world, the MEL 80 Excimer laser from Carl Zeiss, Germany, to deliver best-in-class results
PRK is usually recommended for those who:
  • Not suitable for LASIK /Femto-LASIK or SMILE
  • Have thinner corneas
  • Have a scar on the cornea (due to previous eye infection or injuries)
Laser assisted in situ Keratomileusis (LASIK)
  • Laser-assisted in situ Keratomileusis or LASIK is the 2nd generation of laser vision correction. This technique involves creation of a flap on the cornea for the laser to correct the visual defect
  • LASIK is an FDA approved and effective way to correct vision. The need for wearing eye glasses arises due to changes in the shape of the cornea. LASIK involves using a cold laser beam to reshape the cornea and make it closer to its ideal shape.
  • A flap is created on the corneal surface using precision instrument calledmicrokeratome, following which an excimer laser reshapes the cornea and there by corrects the visual defect.
  • As compared to PRK, the initial discomfort is milder and for much shorter duration. The speed of visual recovery is also relatively faster with LASIK. At Nandadeep, we use the most advanced state-of –the-art laser system from Carl Zeiss, Germany – the world leaders in medical technology. The MEL-80 laser system is designed to deliver high resolution vision with a custom treatment unique to your eyes only. When combined with Nandadeep’s state-of-art operating theatres and highly skilled surgeons, we give each patient the best possible chance for an uncompromisingly superb quality of vision, free from glasses and contacts.
Femtosecond Laser assisted in situ Keratomileusis (FEMTO-LASIK)
  • also known as bladeless LASIK
  • compared to LASIK, corneal flap is created with the help of another cutting laser called Femtosecond laser
  • laser increased the precision and accuracy of flap making as compared to the microkeratome blade
  • allows laser vision correction surgery to become even more safer by adding extra precision

Small Incision Lenticule Extraction (SMILE)

  • no flap, no pain, quick recovery, and fully computer operated by the femtosecond laser
  • The 3rd generation of Laser Vision Correction, ReLex SMILE is a breakthrough in laser technology offering a whole new level of precision, safety and comfort. In fact, you might just experience the world through a whole new lens-your natural ones. ReLex SMILE is a pain free, minimally invasive approach with the advantage of a 100% blade–free laser vision correction. This procedure involves no corneal flaps; refractive changes are made in the intact cornea itself
  • Unlike the conventional procedures, ReLex SMILE involves the creation of an extremely thin 3D layer in your intact cornea, corresponding to your refractive number that needs correction. This is then extracted out through a small keyhole incision of about 2-4mm only. As a result, the cornea gets reshaped to correspond to the ideal shape for correct vision. Entirely laser controlled, it is done in a few seconds- precise, safe and comfortable
  • The ReLEx SMILE technique is performed using the highly precise and advanced VisuMax femtosecond laser from Carl Zeiss AG, Germany. This laser system has impressed both the patients and the physicians alike with its sophisticated technology and its precision and reliability. ReLEx SMILE using VisuMax promises accuracy down to the nearest micrometer precision.
  • Nandadeep Eye Hospital has invested in this amazing state-of-the-art technology to provide the best of the technology and care to our patients. Speak to us to know how SMILE can truly make you smile
Advantages of Relex SMILE
  • The cornea surface is left untouched, preserving its biomechanical strength and stability better than other techniques
  • Inflammation is reduced to negligible as the total laser energy used is up to 10 times lesser than an excimer laser
  • Likeliness of dry eyes is significantly lowered, since no flap is created
  • There is no use of surgical cutting instruments and involves no change of equipment during the treatment
  • Since this procedure is minimally invasive, it involves minimum intervention and therefore less after care is required, enabling you to enjoy your new visual sensation right from day one
Want to use glasses for reading after 40? HOLD ON................!!!!
presbyond peoples with glasses
Are you Aware of PRESBYOND?

Presbyond laser is a treatment for people who have age-related need for reading glasses, known as presbyopia. As we age the natural lens inside our eye loses its flexibility, resulting in loss of the ability for near focusing. The effects of this are usually seen after the age of 40.Presbyond uses excimer laser to sculpt the cornea and focuses the dominant eye for distance and the non-dominant eye for near sight. It is different to traditional monovision or micro-monovision, as the sophisticated wavefront laser profile expands the depth of focus for each eye. This improves your vision whether you are reading a book or driving a car, reducing or eliminating the need for glasses.

Implantable Phakic Contact Lens (IPCL)

The Phakic IOL technique is recommended for patients with moderate to severe myopia, i.e., very high refractive powers (near-sightedness). It is used safely and effectively for the acutely near-sighted who are tired of wearing thick glasses and are not suited for the customized LASIK procedure, because they have low corneal thickness or flat corneas.

In this procedure an intraocular lens, (made of biocompatible material that has been tested and proven fit for implantation for over 50 years), is fixed in front of the natural clear lens — behind the cornea and on top of the iris. The word ‘phakic’ means that the natural crystalline lens is left in the eye. This is important because the natural lens plays an important role in helping the eye adjust between seeing objects that are near and far. This gives the eye another focusing lens that provides high-quality, high-definition vision like a normal eye.

Implantable Phakic Contact Lens
Clear Lens Extraction

This option is not considered for individuals with myopia as literature has suggested increased incidence of retinal detachment after removal of the lens. Though the incidence of retinal detachment is less in the case of hyperopia, this procedure is not recommended in young people with hyperopia since they stand the risk of posterior capsular opacification. Refractive lens exchange with multifocal or monofocal intraocular lens is recommended for high hyperopes over +5 D after the eye of 40 years.
