VOZ & SAFE: Is it the Right Choice for Getting Rid of Glasses?

Wearing specs can be a hindrance to regular activities, such as playing sports or going swimming. Additionally, there is always the chance of misplacing them. With the advent of modern technology, however, there are now ways to reduce the reliance on glasses. To help you find your way to get freedom from glasses, we will discuss the new-age procedures VOZ and SAFE invented at the Dada Laser Eye Institute, Pune. Know how they work and what makes them the right choice to remove glasses.

Elaborating VOZ & SAFE Methods


The Variable Optics Zone (VOZ) is a transforming technique used in the latest LASIK Laser type, Refractive Lenticule Extraction (ReLEx) or Small Incision Lenticule Extraction (SMILE). This new technique is designed to take into account the different-sized pupils of patients. It uses minimal corneal tissue consumption to treat the eyes efficiently. The VOZ technique is designed to use the Scheimpflug imaging system and a specific kind of laser light to improve accuracy. This data is then used to calculate the amount of tissue to be treated, taking into account the patient’s pupil size.


The introduction of SAFE also referred to as Shearing Applied Forced Extraction, has been a major breakthrough in laser vision correction. This next-generation LASIK Laser technology is designed to drastically reduce the risk of Corneal inflammation, thus allowing for a considerably quicker and more comfortable recovery period. Furthermore, it uses much less invasive techniques, relying on natural forces and not requiring extensive tissue manipulation.

Why Choose VOZ & SAFE methods over others?

To get rid of glasses, we have many popular procedures accepted around the world. LASIK LASEK, ICL, and C3R are some of the common techniques doctors recommend for the same. Then what makes VOZ and SAFE different? All these procedures have a high success rate, but VOZ and SAFE have additional benefits.

Benefits of VOZ

The use of VOZ (Variable Optical Zone) for laser eye surgery is a highly beneficial procedure for patients.
  • It decreases the amount of tissue removal, making it a safe procedure that allows your eyes to heal quickly.
  • VOZ can save up to 30% of the tissue in laser eye procedures.
  • This also helps maintain the cornea’s strength, resulting in a safer procedure overall.
  • The decrease in tissue removal also reduces the risk of side effects, making it more comfortable for the patient.
  • Because of its minimal invasiveness, the VOZ technique helps with almost immediate recovery.
  • Moreover, the reduced laser used in the procedure enables it to be completed in a shorter time frame.
  • The need for more invasive procedures, such as Implantable Contact Lenses (ICL), is also decreased with the use of VOZ, making the procedure even more
  • straightforward.
These benefits contribute to making VOZ a highly beneficial procedure for those undergoing laser eye surgery for glasses.

Benefits of SAFE

SAFE is an advanced laser procedure designed to correct vision problems due to refractive errors, such as myopia and astigmatism.
  • This procedure offers numerous benefits for patients wanting to correct their vision without invasive procedures or lengthy recovery times.
  • SAFE is a painless procedure that requires no invasion, making it a bladeless technique.
  • Additionally, it is flapless, meaning no incision or flap is made in the cornea.
  • This procedure is semi-Robotic and utilises computer-based technology to assist with the process, resulting in a reduced procedure time.
  • The recovery rate of SAFE is also much faster than other methods, with most patients being able to resume their daily routine immediately after the procedure.
SAFE is, therefore, a great option for those looking to correct their vision quickly and with minimal discomfort.

Final Words

VOZ and SAFE are the supreme procedures to free yourself from the hassles of wearing glasses. These require negligible invasion and do not damage much corneal tissue. They have a fast recovery period and allow you to indulge in activities for which glasses are a hindrance. If you are planning to go through a glass removal procedure, VOZ and SAFE will certainly be the best choice. Contact Dada Laser Eye Institute and have a safe glass removal journey.

Traditional Methods of Vision Correction

Several traditional glass removal methods have been proven effective. LASIK (Laser-Assisted in Situ Keratomileusis) is one of the more popular vision correction methods. During this procedure, a laser is used to reshape your cornea, which helps people with refractive errors normalise their eye power. Studies have shown that about nine out of ten people with LASIK get a vision that is between 20/20 and 20/40 without the use of glasses or contact lenses. Another traditional method of vision correction is called LASEK, which stands for laser subepithelial keratomileusis. During this procedure, the laser is directed underneath the epithelial layer of the eye to reshape the cornea. For those who do not qualify for LASIK, there is a revolutionary technique that aids in vision correction called ICL, or Implantable Collamer Lens. During ICL, an artificial lens is placed inside the eye to help correct vision. This procedure is more involved and carries more risk, but it can still be an effective method of vision correction for those who are not eligible for LASIK.

VOZ & SAFE A New Technique


The newest innovative Laser surgery for vision correction, called Refractive Lenticule Extraction (ReLEx) or Small Incision Lenticule Extraction (SMILE) utilises a technique called Variable Optic Zone (VOZ) to treat various areas of the cornea. VOZ works by utilising the concept of minimal tissue consumption depending on the size of your pupil. With the use of modern technology, such as the Scheimpflug Imaging System, which uses a special type of laser light for accuracy, the size of the pupil is measured under different lighting conditions. This data is then utilised to decide the amount of tissue in the cornea that needs to be treated by Laser. It uses special software to do the necessary calculations to treat tissue, depending on the size of the pupil, so as to avoid photic phenomena such as glare and halos. This innovation has revolutionised the way we treat vision correction as it is tailored to each individual’s needs.


SAFE (Shearing Applied Force Extraction) is a technique used in modern LASIK lasers such as Refractive Lenticule Extraction (ReLEx) and Small Incision Lenticule Extraction (SMILE) to help minimise the amount of inflammation to the cornea and aid in rapid healing with a rapid visual recovery. This method also eliminates the need for blades and flaps making the surgery painless and reducing the overall procedure time. Those undergoing laser treatment for their vision can resume their regular activities almost immediately after the procedure.

Lifestyle Changes to Maintain Good Eye Health

Good vision is crucial for leading a happy and productive life. Unfortunately, the lifestyles of many people today have caused vision-related problems to be increasingly common. Even though lifestyle changes cannot correct vision, it is an important factor in maintaining eye health.

Eating Nutritious Food

A healthy diet can provide key vitamins and minerals needed to keep the eyes healthy. A balanced diet and getting essential nutrients can help reduce the risk of developing various eye conditions. Omega-3 fatty acids found in fish, nuts, and certain fruits and vegetables can have a positive effect on eye health. Eating healthy foods can also help improve vision and prevent further damage to eyesight. Further, leafy greens such as spinach, kale, and collard greens contain lutein and zeaxanthin, which can help protect the eyes against damage from ultraviolet light. Additionally, antioxidants found in colourful fruits and vegetables can help to prevent damage to the eyes from free radicals.

Regular Eye Exercise

Proper eye exercises can help improve focus, reduce eye strain and maintain good eye health. Exercises such as looking away from the monitor for a few seconds every 15 minutes, blinking regularly, and rotating the eyes in a clockwise and counterclockwise direction can all help improve eye health. Additionally, focusing on distant objects every once in a while helps keep the eye muscles activated. Focusing regularly on objects such as a pen or pencil helps to relax the eye muscles and prevents them from straining. Further, focusing on near and far objects alternately helps to improve the eyes’ ability to focus.

Going for Regular Eye Checkups

If you have a family history of vision problems, getting your eye checked at a regular interval can prove beneficial. It is recommended to get an eye exam every two years, or as recommended by your eye care professional. During the check-up, a comprehensive examination of the eyes is performed to detect any eye conditions or diseases. Regular eye screenings can help detect any potential problems before they become more serious.


It is possible to get rid of glasses with vision correction techniques such as VOZ and SAFE. These techniques involve changes in lifestyle, dietary modifications, and the use of specialised tools to improve one’s vision naturally. With commitment and consistency, individuals can improve their vision and reduce or eliminate their dependence on glasses.
