Corneal Thickness Change Induced by Dozing While Wearing Hydrogel and Silicone Hydrogel Lenses

Autor: Setsuko Kotani, Takashi Hamano, Naoyuki Maeda, Sachiko Mitsunaga, Hikaru Hamano

Publikováno v: Eye & Contact Lens: Science & Clinical Practice. 34:56-60

The physiologic effects on the cornea of dozing while wearing contact lenses were assessed by using central corneal swelling as an index in relation with lens oxygen transmissibility (Dk/t).Two hydrogel lens materials (nelfilcon A and etafilcon A) wi

Videokeratography for quantitative surface analysis of used soft contact lenses

Autor: Naoyuki Maeda, Sachiko Mitsunaga, Kiyoshi Watanabe, Hikaru Hamano, Michael K. Smolek, Stephen D. Klyce

Publikováno v: Japanese Journal of Ophthalmology. 41:235-239

The greater utilization of soft contact lenses calls for the development of new and objective methods of evaluating the optical performance of the different lens types, in situ. We used videokeratography to examine the surface topography of soft cont

Soft and RGP lens corneal swelling and deswelling with overnight wear

Autor: Hikaru Hamano, Yoshitaka Miyanaga, Randall Sakamoto

Publikováno v: International Contact Lens Clinic. 18:214-218

An overnight study was performed to compare the corneal swelling and deswelling for two very different modes of extended wear. A soft disposable lens, Acuvue (Johnson & Johnson), and a high Dk RGP lens, Super EX (Menicon), were investigated. A contac

Publikováno v: Eyecontact lens. 29(4)

Purpose To compare corneal endothelial bleb formation and disappearance processes between rigid gas-permeable (RGP) contact lenses and soft contact lenses (SCL) in the same class of oxygen transmissibility (Dk/L). Methods Experiments were conducted o

Autor: Hikaru, Hamano, Jean T, Jacob, Carl J, Senft, Tamotsu, Hamano, Takashi, Hamano, Sachiko, Mitsunaga, Setsuko, Kotani, Herbert E, Kaufman

Publikováno v: The CLAO journal : official publication of the Contact Lens Association of Ophthalmologists, Inc. 28(2)

To investigate ethnic differences in corneal endothelia bleb formation and corneal swelling during contact lens wear under closed-eye conditions, with the use of lenses of varying oxygen transmissibilities (Dk/L) in Asian and non-Asian subjectsAsian

Corneal thickness measurements with the Topcon SP-2000P specular microscope and an ultrasound pachymeter

Autor: Hikaru Hamano, Stephen C. Kaufman, Hilary W. Thompson, Renee Bovelle

Publikováno v: Archives of ophthalmology (Chicago, Ill. : 1960). 117(7)

To compare the reproducibility of measurements obtained with a new pachymetry instrument, the Topcon specular microscope (Topcon SP-2000P; Topcon America Corp, Paramus, NJ), with those obtained by ultrasound pachymetry.Corneal thickness was measured

Publikováno v: Optometry and vision science : official publication of the American Academy of Optometry. 67(6)

The oxygen transmissibilities (Dk/L) of a set of 48 contact lenses made from 8 different materials were measured by 4 laboratories. The L/Dk measurements from each laboratory were compared and correlated. Samples which were not masked with a fixed fr
