How Technology is Transforming Cataract Eye Surgery in Singapore

Cataract surgery is one of the most common procedures performed worldwide. As technology advances, so do the techniques and tools used to perform it.
At JLE Specialists, biometry and eye-checking technology are used to ensure the removal of cataracts and the replacement with artificial lenses proceeds smoothly. This commitment to utilising the latest technology is reflected in our adoption of industry-forward devices and equipment, such as the IOL Master 700 and the Galilei G4, to improve accuracy, patient outcomes, and recovery times for cataract surgery.

IOL Master 700: For Amped-Up Accuracy in Cataract Surgery

Cataracts, while most commonly seen in older adults, typically those over 55, can also affect individuals before 40 years old. While the exact reasons behind early-onset cataracts are multifaceted, several factors contribute to their development.

The IOL Master 700 is a significant advancement in biometry, the science of measuring the eye. This technology uses swept-source optical coherence tomography (SS-OCT) to provide highly accurate measurements of the eye’s structures, which are crucial for determining the correct power of the intraocular lens (IOL) to be implanted during cataract surgery. The IOL Master 700 is also used to make OCT images and find biometric parameters. It can calculate eye length to calculate intraocular lens power.

IMPACT ON PATIENT OUTCOMES

By providing accurate measurements and detailed visualisation, the IOL Master 700 contributes to improved patient outcomes. Studies have shown that the use of SS-OCT biometry, like the IOL Master 700, leads to more predictable refractive outcomes after cataract surgery.

This means patients are more likely to achieve their desired vision correction, reducing the need for further interventions or corrective eyewear. Minimising refractive surprises not only increases patient satisfaction but also reduces the need for additional corrective procedures, enhancing the overall quality of life after surgery.

The IOL Master 700 also considers angle kappa, the distance between the pupil centre and the visual axis, which is important for determining the best possible calculation and customisation for IOL implant selection. This personalised approach ensures that each patient receives the most appropriate IOL for their individual needs and particular conditions.

The Galilei G4: Comprehensive Eye Assessment for Enhanced Surgical Planning

While the IOL Master 700 focuses on precise biometry, the Galilei G4 complements this technology by providing a comprehensive analysis of the anterior segment of the eye. This device combines Placido disc topography and dual-Scheimpflug tomography to offer a detailed assessment of the cornea and the correction of astigmatism, which are crucial for successful cataract surgery’s refractive outcome. 

IMPACT ON PATIENT OUTCOMES

The Galilei G4’s comprehensive analysis of the cornea contributes to more precise surgical planning and better astigmatic IOL selection. This leads to improved visual outcomes and faster recovery times for patients undergoing cataract surgery. 

The device’s ability to detect subtle corneal irregularities and abnormalities, like keratoconus, in their early stages is particularly significant. Early detection of keratoconus can lead to better treatment outcomes and potentially prevent vision loss, preserving the patient’s long-term eye health.

Furthermore, the Galilei G4 allows for the simulation of visual experience, which may improve surgery planning and refractive outcomes. This feature helps patients understand the potential visual benefits of the surgery and contributes to greater satisfaction with the results. The reduced light intensity used during the Galilei G4 examination is particularly beneficial for patients who may be anxious or have sensitive eyes. This patient-centric feature ensures a more comfortable experience, reducing any potential stress associated with the examination.
