MIGS with iStent: a new and effective way to manage glaucoma

Published on: March 11, 2022

Glaucoma, the second leading cause of blindness worldwide, is usually characterized by an abnormally high eye pressure.

“The eye has a ‘drainage system’, wherein fluid normally flows in and out,” explains Asian Eye Institute Glaucoma, Cataract, and Cornea and Refractive Specialist Dr. Robert Ang, “When this drainage system gets blocked, this fluid can’t flow at its normal rate. This causes the build up in eye pressure, eventually damaging the optic nerve. This is a problem because the optic nerve is responsible for carrying information from the eye to the brain.”

“Any damage to the optic nerve is permanent and can lead to irreversible blindness. To preserve their vision, we strictly monitor the patient’s eye condition through regular checkups and recommend the best possible treatment options,” he adds.

While there is no cure, different treatment options are available today to lower or maintain the eye pressure at a normal level. Typically, glaucoma patients are given prescription eyedrops. Meanwhile, those with advanced cases are recommended to undergo laser, filtering or other traditional surgeries. However, these surgeries may be too invasive, have long recovery and can cause various complications.

Micro-Invasive Glaucoma Surgery (MIGS) with iStent is one of the next generation glaucoma treatments. According to Dr. Ang, MIGS was developed to reduce the complications of most standard glaucoma surgeries. “We make use of a tiny medical implant called iStent to create a bypass between the front part of the eye and its natural drainage pathway. This helps improve the outflow of eye fluid, reducing eye pressure.”

Asian Eye makes use of Glaukos’ iStent Trabecular Microbypass, the first MIGS device that has been proven safe and effective by the U.S. Food and Drug Administration (FDA). Dr. Ang says, “The iStent is so small that you won’t see or feel it. It is also made of surgical-grade titanium, so it likely won’t be rejected by the body. Also, the insertion of iStent takes only about 5 to 10 minutes, so it is minimally traumatic and allows faster recovery. Patients can return to their normal activities more rapidly than the other forms of glaucoma surgery.”

Dr. Ang is a pioneer in the MIGS with iStent procedure here in the Philippines. It is recommended to patients who have difficulty taking medication, experience side effects to or complications from medication, have mild to moderate glaucoma, have undergone or will undergo cataract surgery, and would benefit from reduction of eye pressure or medication.

Often tagged as the silent thief of sight, glaucoma does not manifest any signs or symptoms as it develops. This is why patients are encouraged to get their eyes checked every year, especially if they are over 40 years old, have a family member who had or has glaucoma, previous eye injury or surgery, have taken or is taking steroid eye drops, and are nearsighted or farsighted.

Asian Eye’s Dr. Robert Ang Wins Gold Medal at Cataract Olympics

At the recent American Society of Cataract and Refractive Surgery (ASCRS) Annual Meeting on April 8, 2024, Dr. Robert Ang of Asian Eye was awarded a prestigious Gold medal in the Cataract Olympics for his video presentation titled “Cataract Technology Hurdles.”

Held in Boston, Massachusetts, USA from April 05 to 08, 2024, the annual meeting featured the participation of outstanding ophthalmologists and eye care professionals from across the globe. The Cataract Olympics symposium provided a platform for teams from leading organizations such as ASCRS, APACRS, ESCRS, and LASCRS to showcase their expertise and compete in various cataract categories making Dr. Ang’s achievement even more remarkable.

Dr. Ang’s award-winning video focused on the critical aspect of astigmatism correction during cataract surgery and offered valuable insights into using Toric (astigmatism) IOLs. His impressive win coincides with Cataract Awareness Month this June, a time dedicated to raising awareness about cataracts and educating the public about available treatment options.

This video competition not only showcases the expertise and skills of specialists like Dr. Ang but also provides a platform for sharing knowledge and exchanging ideas with doctors worldwide regarding new technologies and surgical techniques. By leveraging the power of visual media, these educational resources help advance the field of cataract surgery and benefit patients globally.

Cataracts are an age-related eye condition, where the normally clear lens of the eye becomes cloudy. Sometimes, it feels like looking at a fogged-up glass. If not treated, it can lead to blindness. Fortunately, surgery can be done to remove it. The ophthalmologist will remove the lens with cataract and replace it with an IOL. There are different kinds of IOLs available, all designed to improve vision.

Asian Eye takes great pride in the exceptional skills and expertise of their esteemed medical team, exemplified by the contributions of Dr. Robert Ang. Dedicated to providing patients with the highest standard of care, patients can have peace of mind when it comes to cataract surgery and other vision-related procedures at Asian Eye.

Cataract Awareness Month: Reclaim Your Freedom, Restore Your Sight

June is Cataract Awareness Month, and as a leading eye center in the Philippines, Asian Eye aims to celebrate and raise awareness about the importance of cataract screenings and drive more individuals to seek timely treatment for cataracts. Cataracts are a common concern among older Filipinos and one of the major causes of visual impairment. According to the Philippine Eye Research Institute, there are 1.18 million people suffering from cataracts, with roughly 400,000 needing surgery.

Cataracts are the clouding of the eye’s natural lens, which can lead to symptoms such as blurry vision, difficulty seeing at night, and increased sensitivity to glare. It can lead to blindness if left untreated, so it’s essential to have them removed when they begin to interfere with your daily activities, such as driving, watching TV, or cooking.

Cataract surgery is a common procedure that involves removing the cloudy natural lens and replacing it with an artificial intraocular lens. Laser cataract surgery offers several advantages over traditional surgery, and Asian Eye is proud to offer patients with cutting-edge solutions for their eye care needs.

Asian Eye utilizes VICTUS Femtolaser technology from the renowned German brand Bausch + Lomb. This advanced technology is able to break up and remove the cloudy lens using significantly less energy, minimizing the risk of damage to surrounding tissues and promoting quicker healing.

Regular visits to your eye doctor are paramount, as they can advise you on the timing of the surgery and explain the benefits and risks involved. If you have an elderly loved one who complains of cloudy or blurry vision, consider giving them the gift of sight with the following Cataract Screening and Surgery deals:

40% off for one (1) cataract screening

50% off for two (2) or more cataract screenings

20% off on cataract surgery

*if scheduled within one (1) week after the screening or deposit is given within (2) weeks

It’s important to make informed decisions with a trusted eye care specialist and to book an appointment with Asian Eye to take proactive steps towards better vision and eye health.
