Intraocular surgery and dry eye: Understanding the link, minimising the risk and preparing for the future

Dry eye disease (DED) and ocular surface disease (OSD) are increasingly recognised as central factors in contemporary intraocular surgery. As cataract, glaucoma and vitreoretinal procedures advance toward greater refractive precision, patient expectations have risen and tolerance for postoperative visual fluctuation...

Squamous metaplasia of conjunctival epithelial cells with soft contact lens wear versus non-lens wearers

Conjunctiva is composed of non-squamous epithelial cells interspersed with goblet cells, which is a secretory epithelium. Squamous metaplasia is a transformation to non-secretory epithelium, ‘keratinised’ and enlargement of the conjunctival non-goblet cells and relatively shrunken nuclei are seen on impression...

Conventional vs. accelerated cross-linking

The Dresden protocol of 3mW/cm2 irradiance for 30 minutes has been extensively studied and has shown advantageous clinical and topographical results. However, this protocol is time-consuming and therefore accelerated CXL using higher irradiance to shorten treatment duration has emerged. The...

Comparison of central laminar thickness in optic neuropathy and normal eyes

The study compares central laminar thickness (LT) among patients with glaucomatous optic neuropathy (GON), patients with non-GON and normal subjects. The non-GON group comprised eyes with demyelinating optic neuropathy (ON), anterior ischaemic ON, compressive ON, Leber hereditary ON and traumatic...
