Have you made your New Year’s Resolution yet? If not, it’s not too late to include your eye care needs on your list. It would be unfortunate to start the year with blurry eyesight and cease to seize the day with vibrancy and confidence. In this age, technology has advanced drastically and helped millions of visually impaired patients.

According to the statistics gathered by the World Health Organization, approximately 1.1 billion worldwide have some visual impairment, whether nearsightedness, farsightedness, astigmatism, or glaucoma. Multiple programs have been implemented to lessen the rate of visual blindness caused by non-compliance, financial burden, or lack of eye care clinics in the area. Individuals of all ages are encouraged to undergo an eye examination regularly to check for visual acuity to prevent the progression of eyesight conditions. Fortunately, there are a few solutions to this growing issue. For example, eyeglasses and contact lenses can significantly help improve the vision of some individuals. However, these solutions can only temporarily treat poor eyesight. In this growing era of technology, it has dramatically helped patients to have many options to choose from that suit their needs and goals for their eye health.

At EyeOnce Eye Clinic, our medical experts display a deep understanding of the anatomy of the eye, allowing for safer surgery. Through our vast knowledge and experience in eye health and the meticulous care we provide our patients, we produce excellent results that exceed their expectations.


Visual acuity happens when the eye’s retina cannot focus light properly due to the eyeball length and cornea’s shape, leading to blurry or double vision. The underlying causes of visual impairment come in many forms. But the most common factors have something to do with refractive errors. This would include myopia (nearsightedness), hyperopia (farsightedness), and astigmatism.


The prevalence of vision impairments has reached billions worldwide. Since then, numerous studies and case reports have been centered on the underlying causes of visual impairments, and different innovative solutions are presented to prevent and treat such occurrences. There are simple solutions to correcting one’s vision. One may wear graded spectacles or prescription contact lenses to see clearly. Albeit temporary, it can provide a clear vision in an instant. However, some individuals seek permanent results; hence, they undergo surgical solutions to improve their eyesight. The following are the leading vision correction procedures offered by EyeOnce Eye Clinic. Patients who visit EyeOnce Eye Clinic can expect only the best from our premium line of vision correction procedures with guaranteed results.


LASIK might be the most popular method of eye vision correction. It is the abbreviated word for Laser In Situ Keratomileusis, a surgical procedure involving the creation of a corneal flap with a femtosecond laser or cornea reshaping using an excimer laser. LASIK has evolved from various techniques in refractive surgery; for one, it has combined PRK (Photorefractive Keratectomy) and ALK (Automated Lamellar Keratoplasty) methods to develop an innovative approach to improve vision. As a result, LASIK poses numerous potential advantages, such as faster improvement of visual acuity, less pain and discomfort, and quicker recovery time.

On the other hand, LASEK (Laser Epithelial Keratomileusis) involves removing the epithelial layer and correcting far-sightedness. This technique compensates for the disadvantages brought about by LASIK, such as corneal ectasia, epithelial growth, and complications related to creating the corneal flap. Learn more about LASIK/LASEK on our website, which comprehensively discusses it before undergoing the procedure.


Implantable Collamer Lens or ICL Implantation is another option for correcting refractive errors such as myopia and hyperopia. It is usually used in high degrees of refractive error conditions or when corneal surgery is contraindicated. It is a type of posterior chamber intraocular lens first developed by the company STAAR Surgical. They created a patented biomaterial from a polymer and collagen blend called Collamer. Collamer makes the lens lighter and more hydrophilic, allowing a better exchange of gas and nutrients in the eyes.

With these lenses, they are found to provide quicker recovery and satisfying results where reversibility is possible. One case report has also shown that the latest model of ICL can guarantee long-term stability. It gives physiologic balance to the eye’s aqueous humor circulation and prevents additional surgeries done before and after ICL to improve eye vision. At EyeOnce Eye Clinic, the newest, government-approved EVO AQUA ICL is implanted between the eye’s lens and iris to correct myopia. EVO AQUA ICL has features that make it more advantageous than LASIK or PTK. For one, it preserves the cornea and reduces the emergence of dry eye syndrome, night glares, and the risk of glaucoma. To learn more about the procedure of ICL implantation using the EVO AQUA ICL, a comprehensive discussion is found here on our page.


Unlike other methods, CLEAR LASIK surgery uses a low-energy femtosecond laser-powered machine without creating a corneal flap. This gives them the advantage of offering more options to adjust centration and rotation during surgery.  CLEAR LASIK is an abbreviation for Corneal Lenticule Extraction for Advanced Refractive Correction. It works similarly to the SMILE (Small Lenticule Extraction) method, where the laser reshapes the cornea and corrects one’s vision. The laser used by EyeOnce Eye Clinic is called the Ziemer Femto LDV Z8 femtosecond laser. It is the finest and most advanced technology for eye vision correction. The Femto laser technology is much gentler than an excimer laser (exciplex laser) used during LASIK procedures. As a result, it reduces the chances of inflammation and adverse side effects.

CLEAR LASIK does not involve removing the top layers of the cornea, as the femtosecond laser creates a disc-shaped piece of corneal tissue known as the lenticule by generating two thin bubble layers within the cornea’s stromal layer. A minimal incision of approximately 2mm is guaranteed to lessen further adverse effects. CLEAR LASIK is the 4th generation eye correction surgery developed by continuous research and has been intricately performed in various clinics. However, only a few clinics can elaborately perform with the most advanced techniques and knowledgeable surgeons like EyeOnce Eye Clinic.

CLEAR LASIK has the most successful results in correcting eye vision because of its exceedingly superior qualities to other vision correction methods. For one, it uses low energy but faster laser speed allowing the patient to recover quickly. And only three main steps are followed for the CLEAR LASIK procedure to commence.

As laser eye surgery continues innovating and thriving, more advanced techniques are developed to aid in vision correction surgeries without using too many blades and longer operation times. Though LASIK/LASEK and ICL Implantation are also modern solutions to visual impairment, CLEAR LASIK may seem a better option for those prone to particular conditions such as dry eye disorders. CLEAR LASIK can treat many eye diseases other than correcting one’s vision, such as cataracts and keratoplasties.
