Cornea Refractive Lens Services
Dr. Bejan Singh’s Zyoptix laser center at Nagercoil is one of the most advanced
technology center for correction of refractive errors or sight defect in the
What is a refractory error or sight defect?
The most common sight defects are myopia or near sightedness, Hyperopia or long
Lasik is the safest and most accurate method to correct short (Myopia) Long Sight (Hyperopia) Astigmatism (Cylindrical powers) and other corneal scarring
How old is this treatment?
There is a
general misconception that lasik is a new modality of treatement. This is
not correct. Lasik is in existence since 1988, and has already
gained wide acceptance world over, More than 5 million people in USA have
How is Lasik better than
require special care and careful maintenance. Moreover it is a recurring
expenditure. A full 5 years use of contact lenses would cost you almost same as
Is Lasik a Surgery?
Lasik is a very simple procedure done with application of just anesthetic drops. It is just the reshaping of the cornea with the help of cold laser
(Exicimer Laser), with sub micron accuracy. Lasik is not at all a complicated
Who can undergo Lasik?
Any person above the age of eighteen years whose poweris stable for the last one year can undergo this procedure. There is no upper ago limit.
What are the powers Zyoptix100 can correct?
Myopia -1 to 20 diopters. Hyperopia + 1 to + 8 diopters. Astigmatism upto 8 diopters.
How safe is the Lasik treatement?
Lasik is a very safe procedure with accurate and preditable results.
What are the other advantages of Lasik?
No injections. The entire treatement gets over in 10 minutes. Normal activities can be resumed the next day. No need to get admitted in the hospital. No
prolonged medications after the treatment.
What is the Latest treatment for refractory errors?
Zyoptix Laser based on wavefront technology uses systems more precise and less invasive than any other known technique developed so for.
Ø It is the preferred choice for refractive surgery by surgeons worldwide
Ø There is no need for injection, Sutures and Hospitalization.
Ø Clarity of vision within hours of surgery.
Ø Extremely predictable.
Ø Both eyes can be treated on the same day.
Conventional Lasik corrects only Small spherical powers. For those people who have lower prescriptions, without, ‘Astigmatisam’ or irregular corneal curvature.
Conventional Lasik may suffice. Zyopix can correct all powers perfectly and
accurately than lasik.
Zyoptix is considered as the most safeast refractive error correction, since the software attached with the machine is inbuilt with various counter checking
mechanisms. Zyoptix is approved by FDA and is more accepted treatement
Zyoptix 100 Laser
Zyoptix Laser has a higher potential for perfect vision with reduced change for visual compromise. Patients with more complex prescriptions, Unusual Corneal shapes
or who want the best visual outcome will benefit from Zyoptix.
Every Patient’s eye differs in corneal thickness, shape and pupil size. Zyoptix. Technology analyses the entire visual system from the corneal surface through the
crystalline lens of the eye, all the way back to the retina.
The new Aberrometer selectively measures the refractive power of the eye at more than 50 sites. The measurement performed in this way is designed to produce
customized individual result.
Benefits of Zyoptix 100
Ø Zyoptix Laser allowa moreindividual to achieve 6/6 vision.
Ø Zyoptix Laser increasers the opportunity of achieving better than 6/6 Vision.
Ø Reduces risk of re-surgery and glare at night.
In saddition to this extraordinary technology a team of highly skilled surgeons are required to operate it. At Bejan singh Eye Hospital we have some surgeons
specialized in Zyoptiz laser surgery. We also have a dedicated team of support
staff, who assist our surgical team and after our patients though out every
stage of the procedure.
ICL (INTRA OCULAR CONTACT LENS)
Treatment Range The Visian ICL is recommended to correct myopia ranging from -3.0 diopters to ≤ to -15.0 diopters with ≤ 2.5 diopters of astigmatism at the
spectacle plane. The phakic IOL can also be used to reduce severe myopia that is
greater than -15.0 diopters to -20.0 diopters with ≤ 2.5 diopters of myopic
astigmatism at the spectacle plane.
The Visian Toric ICL is recommended to treat myopia ranging from -4.0 diopters to -20.0 diopters with astigmatism of 1 diopter to 4 diopters.
Stable Refractive History
A stable refractive history is also required of the ideal Visian ICL (and Visian TICL*) patient, who must exhibit stability within 0.5 diopter for a minimum of one
year prior to implantation.
Also the patient should have no history of glaucoma, cataracts, Fuch’s dystrophy or keratoconus.
Proper Anterior Chamber Depth
The Visian ICL patient must also have an anterior chamber depth (ACD) of 3.00 mm or greater. The Visian TICL* patient must have an ACD greater than 2.80 mm.
Additional Features of the Visian ICL for Patient Selection
Because no corneal tissue is removed during Visian ICL implantation, patients who have thin corneas and are therefore not considered good candidates for LASIK and
other refractive procedures can be suitable candidates for the Visian ICL.
For patients with severe myopia who are outside of the range for LASIK or PRK, the Visian ICL is the most promising option for high-quality vision, with rapid
recovery, excellent tolerance, and outstanding results.
Patients at high risk for postoperative inflammation may also be suitable Visian ICL candidates.
Because the lenses are made of Collamer, a highly biocompatible material that is used exclusively by STAAR Surgical Company, the Visian ICL is ideal for many
patients who suffer from severe dry eyes or are prone to ocular infection, and
are therefore unable to use traditional contact lenses.
There’s a big difference between “visual acuity” (20/20 vision is considered normal visual acuity) and “visual quality.” Many refractive procedures such as LASIK
offer the promise of improved visual acuity but the quality of your vision may
vary significantly based on the procedure you choose. The Visian ICL provides
vision correction that goes beyond LASIK. It helps you enjoy sharper, clearer,
and more vivid vision, with greater depth and dimension. It’s called High
Definition Visian, and it’s available only with the Visian ICL.
STAAR Surgical Company's Visian ICL has a proven track record of providing improved quality of vision. When compared to other refractive surgical procedures, the
Visian ICL creates sharper vision. The immediate improvement of vision quality
and the remarkably short and painless recovery produces a unique "WOW!" factor
The "High Definition Vision” delivered by the Visian ICL makes this proven, technologically advanced vision correction procedure the choice for patients who need and
expect high quality results. In fact, the U.S. military has embraced the Visian
ICL because of the reliable visual clarity it achieves. The Visian ICL is
clearly the choice for patients with an active lifestyle and those who cannot
accept anything less than the highest quality vision.
