The demands for refractive surgery weigh on achieving the best unaided vision postoperatively. This, in many clinics, lines up with achieving a plano or minimal spherocylindrical manifest refraction. However, in my experience, many patients are complaining of blurred vision after ...
Excess corneal astigmatism can cause visual aberrations, resulting in symptoms of glare, starbursts and halos. Astigmatism has long been difficult to correct with refractive laser surgery. The challenge has been to maximally reduce both corneal and refractive astigmatism while ensuring ...
Keratoconus is the most common primary progressive ectatic condition of the cornea. It is classically described as non-inflammatory, distinguishing it from several other pathologies associated with corneal thinning. Prevalence of this disease varies depending on geographical location, with reports as ...
Cataract surgery has undergone a significant transformation in the last 70 years, becoming a safer and more reliable treatment with better visual outcomes. An important part of this transformation has been the advent of new intraocular lens (IOL) technologies, starting with ...
Approximately 50% of the population aged ≥60 years exhibit >1.0 diopter (D) of corneal astigmatism,1 and 15–29% have >1.5 D.2 If their astigmatism is not corrected at the time of cataract surgery, these patients will require spectacle correction postoperatively. Toric intraocular lenses (IOLs) ...
Over the past two decades, new innovations have led to a dramatic increase in the number of microsurgeries performed in many surgical specialties. However, microsurgery using the traditional binocular microscope can lead surgeons to deleterious neck and back postures that ...
A 34-year-old male presented to the clinic for a second opinion regarding ongoing symptoms of glare, ghosting, starbursts, haloes and reduced contrast sensitivity three years post-laser-assisted in situ keratomileusis (LASIK) surgery. These symptoms were exacerbated under low light conditions, particularly ...
Ocular residual astigmatism The initial step of planning any refractive laser treatment that requires correction of astigmatism is to calculate the difference in magnitude and axes between the refractive cylinder at the corneal plane, and the corneal astigmatism – that is ...
Cataract surgery had undergone major improvements in different areas over the last 10 years. New intraocular lens (IOL) designs and fourth generation IOL formulae are available, allowing spectacle independence for many patients. Femtosecond laser-assisted cataract surgery (FLACS) has been introduced, and ...
Through the centuries, ceaseless innovation has advanced cataract surgery – the most frequently performed operation on earth – from Daviel’s lens extraction, to Ridley’s intraocular lens (IOL) implantation, to Kelman’s phacoemulsification, and now to femtosecond laser assisted techniques.1 Femtosecond ...
Harvard Business School professor Clayton Christensen popularized the concept of disruptive innovation to explain why the most successful companies eventually fail. While the leading companies continue to develop better and more expensive technology, they fail to anticipate a sea change ...
Q: What is the optimal procedure for pre- and intraoperative imaging of the eye during toric IOL implantation? Toric IOLs have perhaps enjoyed the greatest reproducible success of any premium lens type in use over the past decade. However, their ...
Accuracy in intraocular lens (IOL) calculations and postoperative outcomes has taken on another level with the availability of toric IOLs. The ability to correct corneal astigmatism at the time of cataract surgery reduces the need for spectacles postoperatively making the ...
With increasing patient expectations and cataract surgery being regarded as a refractive procedure, multifocal intraocular lenses (IOLs) are one of the most effective ways of achieving a good visual acuity at distance, intermediate and near. However, precise biometry and astigmatism ...
This research is primarily focused on the influences on enhancements in laser vision correction during the perioperative period. As surgeons we always strive to enhance technology while trying to improve outcomes. However, this study was a prospective look at what ...
Several factors point to a potentially precipitous rise in the need for cataract surgery in the near future: population growth, increased awareness of and demand for excellent unaided vision, and the collateral benefits of improved vision after surgery. In 2015, there ...
Cross-linking (CXL) is a technique originating from the synthetic polymer field that can be used to alter a polymer’s physical and mechanical properties. It was first proposed for corneal use by Theo Seiler from Germany in 1995 and was later ...
With the increasing use of advanced technology intraocular lenses (ATIOLs), the need for careful preoperative assessment is critical for both determination of a patient’s candidacy for an ATIOL and the identification of patients who are not appropriate candidates.1 Currently, ...
