A new method of cornea modulation with excimer laser for simultaneous correction of presbyopia and ametropia.

Purpose: To investigate the outcomes of simultaneous correction of presbyopia and ametropia by a bi-aspheric cornea modulation technique, based on the creation of a central area hyperpositive for near vision and leaving the pericentral cornea for far vision in hyperopic, emmetropic, and myopic presbyopic patients.

Setting: Sixty eyes of 30 patients were treated with the PresbyMAX technique by one surgeon (D.U.

Laserinterferometric measurements of accommodative changes in the position of an optic-shift intraocular lens.

Purpose: To measure optically and pharmacologically induced movement of an optic-shift intraocular lens (HumanOptics 1CU).

Methods: The change in position as well as the accommodative effect of the 1CU was determined using an anterior chamber laser interferometer (Zeiss ACMaster) in 15 eyes of 9 patients. Accommodation was induced by optical stimulus and pharmacologically by pilocarpine 2%.

Potentially accommodating 1CU intraocular lens: 1-year results in 553 eyes and literature review.

Purpose: To investigate the advantages, clinical outcomes, and safety after implantation of the 1CU (HumanOptics AG) optic shift intraocular lens (IOL) in comparison with a conventional monofocal IOL.

Methods: In a prospective non-randomized study, 553 eyes implanted with the 1CU IOL were examined. In a control group, a monofocal posterior chamber IOL (MCTE, Dr Schmidt) was implanted in 219 eyes.

Possible air embolism during eye surgery.

We report a case of possible air embolism during a three-port pars plana vitrectomy and air-fluid exchange of the vitreous cavity of the eye. After the start of intraocular air flushing, sudden tachycardia, a decrease in oxygen saturation and end-tidal carbon dioxide tension, and a distinct "mill-wheel" murmur were observed. Venous air embolism was suspected but other sources of air entry into the circulation and a thromboembolic event were excluded.
