Subjective health expectations of patients with age-related macular degeneration treated with antiVEGF drugs.

BACKGROUND: Subjective expectations regarding future health may influence patients' judgement of current health and treatment effects, as well as adherence to therapies in chronic diseases. We aimed to explore subjective expectations on longevity and future health-related quality of life (HRQOL) of patients with age-related macular degeneration (AMD) treated with antiVEGF injections and analyse the influencing factors. METHODS: Consecutive AMD patients in two ophthalmology centres were included. Demographics, clinical characteristics and informal care utilisation were recorded. Current health was evaluated by the EQ-5D generic health status questionnaire and time trade-off (TTO) methods. Happiness was measured on a visual analogue scale (VAS). Subjective life-expectancy and expected EQ-5D status at ages 70, 80 and 90 were surveyed. T-test was applied to compare subgroups and Pearson correlations were performed to analyse relationships between variables. RESULTS: One hundred twenty two patients were involved (females 62%) with a mean (SD) age of 75.2 (7.9) years and disease duration of 2.9 (2.5) years. The majority were in AREDS-4 state, the better eye's ETDRS was 64.7 (15.4). EQ-5D and TTO revealed moderate deterioration of health (0.66 vs. 0.72, p = 0.131), happiness VAS was 6.3 (2.2). Correlation between EQ-5D and ETDRS was moderate (R = 0.242, p < 0.05) and having both versus one eye in AREDS-4 resulted lower TTO (0.68 vs. 0.83; p = 0.013). Subjective life-expectancy did not differ significantly from statistical life-expectancy and had no significant impact on TTO. The self-estimated mean EQ-5D score was 0.60, 0.40 and 0.24 for ages 70, 80 and 90 which is lower than the population norm of age-groups 65-74, 75-84 and 85+ (0.77, 0.63 and 0.63, respectively). Age, gender, current EQ-5D, need for informal care and happiness were deterministic factors of subjective health expectations. CONCLUSION: AMD patients with antiVEGF treatment have comparable HRQOL as the age-matched general public but expect a more severe deterioration of health with age. Older patients with worse HRQOL have worse subjective expectations. Exploring patients' health expectations provides an opportunity for ophthalmologists to correct misperceptions and improve the quality of AMD care. Further studies should provide evidences on the relationship between subjective expectations and actual health outcomes, and on its impact on patients' AMD-specific health behaviour.

INTRODUCTION: Femtosecond laser-assisted cataract surgery improved the results of cataract surgeries. AIM: Outcome analysis of femtosecond laser-assisted cataract surgery using the novel 2.16 software and the SoftFit(®) Patient Interface. METHOD: The novel software and the newly developed Patient Interface were used in 100 eyes of 100 patients. RESULTS: Length of femtosecond laser pretreatment decreased to 45-60 seconds. The smaller size of the new patient interface resulted in easier docking even on pediatric eyes. Suction force used for docking decreased from 40-50 mmHg to 16-20 mmHg. Incidence rate of subconjunctival suffusion decreased from 40% to 15-20% and its clinical severity was reduced, too. No corneal microfolds evolved, thus the incidence rate of the free-floating capsulotomies increased from 30% to 97%. The total energy of femtosecond laser pretreatment was decreased by almost 50%. Corneal wounds had the desired structure, and they were easy to open and closed precisely. CONCLUSIONS: The SoftFit(®) patient interface and the novel software widened the possible uses of the femtosecond laser-assisted cataract surgery, e.g. in pediatric ophthalmology. Innovations improved the safety and the predictability of the method.

Evaluation of femtosecond laser-assisted and manual clear corneal incisions and their effect on surgically induced astigmatism and higher-order aberrations.

PURPOSE: To evaluate femtosecond laser-assisted and manual clear corneal incisions and their effect on surgically induced astigmatism (SIA) and corneal higher-order aberrations (HOAs). METHODS: In a prospective randomized study, conventional phacoemulsification with a 2.8-mm clear corneal incision using a disposable keratome was performed in 20 eyes of 20 patients (manual group), and femtosecond laser-assisted cataract surgery with a 2.8-mm biplanar clear corneal tunnel created by a femtosecond laser (LenSx; Alcon Laboratories, Inc., Aliso Viejo, CA) was performed in 20 eyes of 20 patients (femtosecond laser group). Corneal topography readings and corneal wavefront aberrations (diameter: 9.0 mm) were obtained using a Scheimpflug camera (Pentacam HR; Oculus Optikgerate, Wetzlar, Germany) preoperatively and 3 months postoperatively. RESULTS: There was no significant difference in SIA between the groups (femtosecond laser group: 0.47 ± 0.13 vs manual group: 0.41 ± 0.14; P = .218), but the axis deviation of the SIA axis from the previously planned axis was significantly smaller in the femtosecond laser group compared to the manual group (4.47°± 2.59° vs 7.38°± 4.72°, respectively; P = .048). Corneal HOAs increased significantly in both groups (femtosecond laser group: 0.13 ± 0.09 to 0.18 ± 0.12, P = .025; manual group: 0.13 ± 0.05 to 0.15 ± 0.05, P = .002), but preoperative and postoperative values did not differ significantly between them (P = .472 and .078, respectively). Lower-order and total corneal aberration values remained stable in both groups (P > .05). CONCLUSIONS: There was no difference in SIA and induced HOAs between manual and femtosecond laser-created clear corneal incisions.
