Nonlinear aspheric ablation profile can treat presbyopia
Presbyopia, in combination with myopia, hyperopia and emmetropia, can be effectively and safely treated by Presbyopic LASIK that uses a new nonlinear aspheric ablation profile. This profile increases the depth of field of the eye, Dan Z. Reinstein, MD, MA(Cantab), FRCSC, FRCOphth said while presenting a study on nonlinear aspheric presbyopic micro-monovision at a symposium sponsored by Carl Zeiss Meditec during the American Society of Cataract and Refractive Surgery meeting in San Francisco.

A novel technology called Zyoptix Advanced Control Eyetracking (ACE) can emerge as an effective treatment for the treatment of astigmatism and severe myopia. The innovative technique has the ability to track eyeball’s rotation during a laser eye surgery. Earlier, eye rotation during surgery influenced the predictability of surgical outcomes. That is why doctors discouraged patients of short-sightedness and astigmatism from going for LASIK. Designed to advance the patient safety, ACE also adjusts the laser ablation pattern for the duration of the laser surgery.
In a study designed to compare the effects of contact lens wear versus spectacle wear on children on their sight, the use of soft contact lenses does not, clinically, accelerate myopic progression in children. These results, combined with earlier data on the safety of soft contact lenses in children, make a strong case that children can safely wear soft contact lenses. The author of the study that was sponsored by Johnson & Johnson Vision Care, Dr. Jeffrey J. Walline presented results at the Association for Research in Vision and Ophthalmology meeting. After using contact lenses for 3 years, the contact lens wearers weren’t more nearsighted than the spectacle wearers.
