“…The health and integrity of cornea and lens are critical for normal vision. Despite considerable advancement in surgical technology, intraocular lens design, and biometry calculation for cataract surgery ( Liu et al, 2017 ; Ting et al, 2017 ; Brandsdorfer and Kang, 2018 ) cataract remains the leading cause of reversible blindness in the world, affecting approximately 12.6 million people globally ( Flaxman et al, 2017 ). On the other hand, corneal opacity represents the 5th leading cause of blindness, with 1.3 million people being affected ( Flaxman et al, 2017 ).…”

The simultaneous maturation of multiple digital and telecommunications technologies in 2020 has created an unprecedented opportunity for ophthalmology to adapt to new models of care using tele-health supported by digital innovations. These digital innovations include artificial intelligence (AI), 5th generation (5G) telecommunication networks and the Internet of Things (IoT), creating an inter-dependent ecosystem offering opportunities to develop new models of eye care addressing the challenges of COVID-19 and beyond. Ophthalmology has thrived in some of these areas partly due to its many image-based investigations. Tele-health and AI provide synchronous solutions to challenges facing ophthalmologists and healthcare providers worldwide. This article reviews how countries across the world have utilised these digital innovations to tackle diabetic retinopathy, retinopathy of prematurity, age-related macular degeneration, glaucoma, refractive error correction, cataract and other anterior segment disorders. The review summarises the digital strategies that countries are developing and discusses technologies that may increasingly enter the clinical workflow and processes of ophthalmologists. Furthermore as countries around the world have initiated a series of escalating containment and mitigation measures during the COVID-19 pandemic, the delivery of eye care services globally has been significantly impacted. As ophthalmic services adapt and form a “new normal”, the rapid adoption of some of telehealth and digital innovation during the pandemic is also discussed. Finally, challenges for validation and clinical implementation are considered, as well as recommendations on future directions.

“…AL refers to the distance from the front most surface of the cornea to the surface of retinal pigment epithelium when using an optical measurement method [3]. As an important indicator among the ocular biological parameters, the accuracy of AL measurement is directly related to the prevention, diagnosis and treatment of various ophthalmic diseases such as ametropia [4], cataracts [5], glaucoma [6], residual silicone oil [7], macular edema [8], strabismus and amblyopia [9,10] and in other clinical applications [11,12]. Ametropia of the human eye is often manifested as hyperopia, myopia and astigmatism, among which hyperopia and myopia are characterized by changes in the AL [13][14][15][16].…”

In order to meet the demands of myopia prevention, as well as the increasing needs of measurement for refractive and cataract operations in China, a new axial length (AL) measurement system combining an improved Twyman-Green interferometer with digital signal processing has been established. The ALs of 33 eyes of different optical refractive subjects (À8.50~0.50 D) were measured with the New AL and intraocular lens (IOL) master. The repeatability of measurements with the New AL was assessed using coefficient of variation (CoV) and intra-group correlation coefficient (ICC). Comparison, correlation, linear regression and agreement of AL between devices were analyzed. There was good repeatability (CoV = 0.0617%, ICC = 0.9999) with the New AL and great agreement has been obtained with both devices. These show that the New AL is capable of providing precise AL values over the normal AL range compared to the IOL master, and indicate that the New AL developed can be used for routine clinical AL measurements.

“…Cataract surgery is one of the most commonly performed surgeries worldwide, with approximately 20 million procedures being performed annually. With the advancement of phacoemulsification technology, intraocular lens designs and power calculation and surgical techniques, 1,2 patients' expectation of good visual and refractive outcomes following cataract surgery is continually rising. 3 This is reflected by the lower preoperative visual impairment threshold and the rising cataract surgery rates observed in many countries.…”

Acute corneal perforation 1 week following uncomplicated cataract surgery: the implication of undiagnosed dry eye disease and topical NSAIDs

Dry eye disease is a common ocular surface disease in patients who are undergoing cataract surgery. The significance of dry eye disease is often underestimated or overlooked during preoperative assessment of cataract. We report an 80-year-old patient, with a background of seropositive rheumatoid arthritis and diabetes, who presented with an acute corneal melt and perforation associated with undiagnosed dry eye disease and use of topical ketorolac 1 week following an uncomplicated cataract surgery. The patient underwent repeated corneal gluing for corneal perforation and was subsequently diagnosed and treated for bilateral moderate-severe dry eye disease. This case highlights the importance of meticulous preoperative assessment and management of the ocular surface, especially in patients with systemic diseases such as rheumatoid arthritis and diabetes prior to cataract surgery. The implication of the use of topical nonsteroidal anti-inflammatory drugs following cataract surgery – which might have contributed to the process of corneal melt in our case – is also discussed.

Improving accuracy for intraocular lens selection in cataract surgery

Abstract: As cataract surgery continues to be one of the most commonly performed surgeries in the United States, it is important to ensure that the most accurate technology, IOL formula, and surgical planning is utilized.
