Table 1 Advantages of 3D system for retinal detachment surgery

Illumination

Digital enhancement of the image, lower illumination levels and, thus, reduced risk of phototoxicity

Depth of field

Enhance depth of field and amplified stereopsis allows better wider view since multiple planes are contemporary in focus

HDRi

Reduced glare of the instruments and even image brightness

Digital filtering

Filters enable the surgeon to have a better view of intraocular structures (e.g. green filter for vitreous or blood)

Education

Surgical team has the same view of the surgeon

ergonomics

Surgeon maintains an heads up position with a less rigid and more comfortable posture

Less asthenopia

Viewing through the eyepiece for a long time may induce asthenopia due to concentration and prolonged accommodation. Since 3D systems does not require near vision, it may reduce asthenopia
