There is provided a glaucoma surgery visualization apparatus. The apparatus has a goniolens which is rotationally coupled to a novel scleral retention device. The apparatus allows for viewing of the irido-corneal angle structures of the eye and related surgical procedures. The scleral retention device uses vacuum to temporarily adhere the apparatus to the sclera. Surgical apertures allow for surgical access, while the goniolens can rotate within the scleral retention device to facilitate proper viewing of the irido-corneal angle structures before, during and after surgery. An optional light source serves to illuminate the field of viewing to further assist the surgeon during various procedures that involve the glaucoma surgery visualization apparatus.
