New applanation tonometer for myopic patients after laser refractive surgery

Comparison of intraocular lens power calculation methods after myopic laser refractive surgery without previous refractive surgery data.

PURPOSE To compare the accuracy of intraocular lens (IOL) power calculation methods for post-myopic excimer laser surgery patients without previous refractive surgery data using the Holladay IOL Consultant Program and the American Society of Cataract and Refractive Surgery (ASCRS) IOL Power Calculator. SETTING Wang Vision Cataract and LASIK Center, Nashville, Tennessee, USA. DESIGN Case ser...

The effect of humidity and temperature on visual outcomes after myopic corneal laser refractive surgery

OBJECTIVE To determine whether procedure room environmental conditions are associated with outcomes after myopic laser in situ keratomileusis (LASIK) or laser-assisted keratomileusis (LASEK). DESIGN Retrospective chart review. PARTICIPANTS Eight hundred sixty-three eyes of 458 consecutive patients at a university-based academic practice. METHODS We reviewed the medical records of consecut...

Optimum corneal asphericity of myopic eyes for refractive surgery

In this work, an improvement to the Munnerlyn formula used in refractive surgery is proposed by selecting the final corneal asphericity. A theoretical optical analysis has been performed by adopting the RMS (root mean square) spot size as a merit function. Two different sets of myopes having refractive errors ranging up to 7D have been tested. The results show that a corneal asphericity of arou...

The application of wide-field laser ophthalmoscopy in fundus examination before myopic refractive surgery

BACKGROUND To evaluate wide-field laser ophthalmoscopy (Optomap 200Tx) for screening retinal lesions before myopic refractive surgery. METHODS Seventy-eight eyes of 78 consecutive refractive surgery candidates were included in this study. All subjects underwent Optomap 200Tx, mydriatic slit-lamp lens examination and the Goldmann three-mirror contact lens examination, which was considered as t...
