Subjective satisfaction in long-term orthokeratology patients
Santolaria Sanz, Elena; Cerviño, Alejandro; Queirós, A.; Brautaset, Rune; González-Méijome, José ManuelPurpose: To AU3 evaluate the subjective satisfaction in visual stability, night vision complains, and light distortion phenomena, and also the number of hours and days per week of lens wear, in patients with myopia undergoing orthokeratology (OK) treatment for at least 1 year. Methods: A visual analog scale (VAS) questionnaire containing 18 items was administered to 44 patients, 29 women and 15 men (mean age, 2...

Pauné, Jaume; Queirós, A.; Quevedo, L.; Neves, Helena; Ferreira, Daniela Lopes; González-Méijome, José Manuel"Article in press". Available online 11 September 2014; Purpose: To evaluate the performance of two experimental contact lenses (CL) designed to induce relativeperipheral myopic defocus in myopic eyes.Methods: Ten right eyes of 10 subjects were fitted with three different CL: a soft experimental lens (Exp-SCL), a rigid gas permeable experimental lens (ExpRGP) and a standard RGP lens made of the same material(St...
Validation of a method to measure light distortion surrounding a source of glare
Neves, Helena Isabel Ferreira; Araújo, Rute Juliana Ferreira Macedo; Rico-del-Viejo, L.; Silva, Ana Carolina; Queirós, A.; González-Méijome, José ManuelOur objective was to validate a new device dedicated to measure the light disturbances surrounding bright sources of light under different sources of potential variability. Twenty subjects were involved in the study. Light distortion was measured using an experimental prototype (light distortion analyzer, CEORLab, University of Minho, Portugal) comprising twenty-four LED arrays panel at 2 m. Sources of variabil...
Myopia control with a novel peripheral gradient soft lens and orthokeratology: ...
Pauné, Jaume; Morales, Hari; Armengol, Jesús; Quevedo, L.; Ribeiro, Miguel António Faria; González-Méijome, José ManuelObjective. To evaluate the degree of axial elongation with soft radial refractive gradient (SRRG) contact lenses, orthokeratology (OK), and single vision (SV) spectacle lenses (control) during a period of 1 year before treatment and 2 years after treatment. Methods. This was a prospective, longitudinal, nonrandomized study. The study groups consisted of 30, 29, and 41 children, respectively. The axial length (A...

Influence of climate on clinical diagnostic dry eye tests: pilot study
Tesón, Marisa; López-Miguel, Alberto; Neves, Helena; Calonge, Margarita; González-García, María J.; González-Méijome, José ManuelPurpose. To analyze dry eye disease (DED) tests and their consistency in similar nonsymptomatic population samples living in two geographic locations with different climates (Continental vs. Atlantic). Methods. This is a pilot study including 14 nonsymptomatic residents from Valladolid (Continental climate, Spain) and 14 sex-matched and similarly aged residents from Braga (Atlantic climate, Portugal); they were...
Efficacy of a gas permeable contact lens to induce peripheral myopic defocus
Pauné, Jaume; Queirós, A.; Ferreira, Daniela Lopes; Ribeiro, Miguel António Faria; Quevedo, L.; González-Méijome, José ManuelPurpose. The purpose of this work was to evaluate the potential of a novel custom-designed rigid gas permeable (RGP) contact lens to modify the relative peripheral refractive error in a sample of myopic patients. Methods. Fifty-two right eyes of 52 myopic patients (mean [TSD] age, 21 [T2] years) with spherical refractive errors ranging from j0.75 to j8.00 diopters (D) and refractive astigmatism of 1.00 D or les...
Peripheral refraction with eye and head rotation with contact lenses
Ferreira, Daniela Patrícia Lopes; Neves, Helena Isabel Ferreira; Ribeiro, Miguel António Faria; Queirós, A.; Fernandes, Paulo Rodrigues BotelhoPurpose: To evaluate the impact of eye and head rotation in the measurement of peripheral refraction with an open-field autorefractometer in myopic eyes wearing two different center-distance designs of multifocal contact lenses (MFCLs). Methods: Nineteen right eyes from 19 myopic patients (average central M ± SD = −2.67 ± 1.66 D) aged 20–27 years (mean ± SD = 23.2 ± 3.3 years) were evaluated using a Grand-Seiko...
Differences in dry eye questionnaire symptoms in two different modalities of co...
García-Porta, Nery; Rico-del-Viejo, L.; Martin-Gil, Alba; Carracedo, Gonzalo; Pintor, Jesús; González-Méijome, José ManuelPurpose. To compare the ocular surface symptoms and signs in an adult population of silicone-hydrogel (Si-Hy) contact lens (CL) wearers with another modality of CL wear, overnight orthokeratology (OK). Materials and Methods. This was a prospective and comparative study in which 31 myopic subjects were fitted with the same Si-Hy CL and 23 underwent OK treatment for 3 months. Dry eye questionnaire (DEQ) was fille...

González-Méijome, José Manuel; Ribeiro, Miguel António Faria; Ferreira, Daniela Patrícia Lopes; Fernandes, Paulo Rodrigues; Carracedo, GonzaloPurpose: The purpose of this study was to evaluate the effect of orthokeratology for different degrees of myopia correction in the relative location of tangential (FT) and sagittal (FS) power errors across the central 70 of the visual field in the horizontal meridian. Methods: Thirty-four right eyes of 34 patients with a mean age of 25.2 ± 6.4 years were fitted with Paragon CRT (Mesa, AZ) rigid gas permeable co...
