Fulla??face skin resurfacing using a combination of fractional and full spot ablative 2940??nm erbium laser
摘要： BACKGROUND: Full-field deep ablative laser resurfacing is a popular method for skin rejuvenation due to maximum improvement in a single treatment. However, it is associated with disadvantages such as pain, prolonged erythema, swelling, crusting, infections, pigmentary changes, and scarring. Patients are increasingly seeking less invasive options with comparable effect. AIMS: The aim of this retrospective study was to evaluate the safety and efficacy of full face resurfacing using a combination of full spot and fractional erbium (Er:YAG) laser resurfacing. PATIENTS/METHODS: 109 patients, mostly females over 50 years old, were treated with a two phase protocol: full spot ablation (5 J/cm2, three passes) and fractional ablation (132 J/cm2, 5% coverage, 3 passes). We recorded time to re-epithelization and duration of post-treatment erythema. Any side effects observed at follow-up or reported by the patient were recorded. Patient satisfaction questionnaire and blinded evaluation of pre and post treatment photographs were used to assess efficacy. RESULTS: A single session was performed in 96% of cases. Post-operative re-epithelization lasted on average 6.4±2.9 days. Post-treatment erythema lasted on average 13.8±15.2 days. One patient had hyperpigmentation, one infection, one hypo-pigmentation, and one ulcer. All side effects resolved without complications. According to the blinded assessment of photographs 78% of patients showed improvement. 97% of patients were satisfied with the results of the treatment. CONCLUSIONS: A combination of fractional and full spot ablative Er:YAG laser is a safe and effective option for full face resurfacing.

Visual, aberrometric, photic phenomena, and patient satisfaction after myopic wavefront-guided LASIK using a high-resolution aberrometer
摘要： The purpose of this study was to evaluate the visual, refractive, and aberrometric outcomes as well as the level of patient satisfaction and photic phenomena after myopic laser in situ keratomileusis (LASIK) surgery using wavefront-guided (WFG) ablations based on measurements obtained with a high-resolution aberrometer. This study was a prospective analysis including 253 eyes of 127 patients (aged between 19 years and 54 years) undergoing WFG LASIK using the STAR S4 IR Excimer Laser System combined with the iDesign System and iFS Femtosecond Laser. Visual, refractive, and aberrometric outcomes during a 2-month follow-up as well as patient satisfaction and photic phenomena were evaluated by means of a questionnaire. A total of 85% (215/253) and 99% (251/253) of eyes achieved a postoperative (Postop) uncorrected distance visual acuity of 20/16 and 20/20, respectively, and all eyes achieved an uncorrected distance visual acuity of 20/25. Postop spherical equivalent values were within ±0.25 D and ±0.50 D in 97% and 100% of eyes, respectively. Likewise, manifest cylinder was <0.25 D in 97% (245/253) of eyes. A statistically significant reduction was found in the total root mean square (P<0.001) and in the level of primary spherical aberration (P=0.001). Postop difficulties related to vision were graded as minimal, with low levels of photic phenomena and high levels of patient satisfaction. The level of difficulty to perform daily activities and the level of glare perceived by patients while driving car were significantly decreased (P<0.001). WFG LASIK surgery using the technology evaluated is predictable and effective for the correction of myopia and leads to high levels of patient satisfaction.

Use of Expectation Disconfirmation Theory to Test Patient Satisfaction with Asynchronous Telemedicine for Diabetic Retinopathy Detection
摘要： Objective. The purpose of the study is to extend research on patient satisfaction with telemedicine services by employing the theoretical framework of Expectation Disconfirmation Theory (EDT) for diabetic retinopathy screenings focusing on rural patients. Method. Adult subjects (n=220) with diabetes were recruited from a single family practice office in rural Iowa. Subjects completed a “pre” survey concerning their forward-looking perceptions of telemedicine prior to using telemedicine for detection of diabetic retinopathy and a “post” survey after they received recommendations from the distant ophthalmologists. Results. All hypotheses of the EDT model were supported. Patient satisfaction is influenced by both patients’ expectations (P<.001) and disconfirmation of expectations (P<.001), and patient satisfaction has a positive impact on patient preference for telemedicine services (P<.001). Overall, patients who received telemedicine services were highly satisfied with telemedicine and developed a favorable disposition towards telemedicine services. Conclusions. The EDT model is a viable framework to study patient satisfaction of telemedicine services. While previous feasibility studies have shown that telemedicine for diabetic retinopathy screenings yields diagnostic efficacy, this study applies a theoretical framework to demonstrate the viability of telemedicine for diabetic retinopathy screenings in rural areas.

Long-term results of a diffractive trifocal intraocular lens: Visual, aberrometric and patient satisfaction results
摘要： Purpose: To evaluate the long-term objective and subjective results of a trifocal intraocular lens. Methods: Prospective observational study enrolling 24 eyes that underwent uneventful microincisional cataract surgery with bilateral implantation of a diffractive trifocal intraocular lens (FineVision Micro F, PhysIOL, Belgium). After a mean follow-up period of 60 ± 2 months, patients answered the 10-item Near Activity Vision Questionnaire (NAVQ-10) and were assessed for uncorrected and corrected distance, intermediate and near visual acuity, defocus curve, light-distortion analysis, and total ocular aberrometry with a pyramidal wavefront sensor (Osiris, CSO, Italy). Results: There was significant improvement of uncorrected visual acuity at all distances in all eyes (p < 0.01). The distorsion index and best-fit circle radius were significantly lower in binocular conditions (p = 0.02). Mean Rasch score at NAVQ-10 was 16.29 ± 11.57. Patients reported to be completely, very, and moderately satisfied with their uncorrected near vision in 67%, 25%, and 8% of cases, respectively. We found no significant correlation between patient satisfaction scores at near vision satisfaction questionnaire and other variables such as light-distortion analysis or wavefront aberrometry parameters. Conclusion: The studied diffractive trifocal intraocular lens provides good and stable long-term results for distance, intermediate, and near vision, with high levels of patient satisfaction at long-term follow-up. The intraocular lens’ light-distortion effect is less disturbing in binocular conditions and may have its perception down-modulated by neuroadaptation over time.

Clinical Results and Optical Quality of Diffractive Multifocal Intraocular Lens
摘要： Purpose: To compare postoperative clinical outcomes, optical quality, and patient satisfaction between two types of diffractive multifocal intraocular lens (IOL, Acri Lisa 366D and Acrysof ReSTOR +3.00 D). Methods: In a total of 68 eyes, one of two diffractive multifocal IOL (Acri Lisa 366D and Acrysof ReSTOR +3.00 D) was implanted after cataract extraction. Visual acuity was measured postoperatively at one week, 1 month, and 6 months. Contrast sensitivity, wavefront aberration, and visual function were determined via questionnaire at postoperative 1 month. Results: Intermediate visual acuity of Acri Lisa 366D and Acrysof ReSTOR at 6 months were 0.31 ± 0.14, and 0.24 ± 0.11 (log MAR), respectively. At 6 months, near and distant visual acuity results showed no significant differences between the two groups. The photopic contrast sensitivity of Acri Lisa 366D at 6 cycles/degree was 55.36 ± 7.40 and showed significant differences with Acrysof ReSTOR (47.25 ± 9.67). The mesopic contrast sensitivity values of Acri Lisa 366D and Acrysof ReSTOR were 40.26 ± 11.38 and 28.97 ± 10.45, respectively, and the spherical aberration values were 0.037 ± 0.039 μm and 0.105 ± 0.066 μm. The spherical aberration of Acri Lisa 366D was significantly lower than that of Acrysof ReSTOR. Total and high order aberration, coma, and trefoil show no significant differences between the two groups. Conclusions: The Acri Lisa 366D multifocal IOL showed better contrast sensitivity and spherical aberration compared to Acrysof ReSTOR multifocal IOL, which had an effective intermediate visual acuity.
