“…By comparison, the National Eye Institute Visual Function Questionnaire-25 (or -39) is a more general instrument measuring health-related quality of life related to disturbances in visual function [23, 24]. The VF-14 scale, which was also developed in cataract surgery studies [25, 26], was considered, but it does not evaluate all the patients’ perceptions and independence from glasses that the TyPE does. For these reasons, we used the TyPE.…”

Background/Aim: To evaluate distance and near vision-related benefit after implantation of ReSTOR® multifocal intraocular lenses (IOLs) following cataract surgery. Methods: Two prospective open-labeled nonrandomized studies were pooled. Patients’ perception of benefit was assessed with the TyPE, administered at baseline and after each eye surgery. Results: A total of 499 patients received ReSTOR IOLs, and 173 received monofocal IOLs. The distance vision of monofocal and ReSTOR patients improved equally with and without glasses. A greater improvement in near vision without glasses was reported by ReSTOR-implanted patients as early as after the 1st eye surgery (p < 0.0001). More ReSTOR patients than monofocal patients reported independence from glasses after the 1st eye surgery (64 vs. 52%; p = 0.0002). This difference had increased after the 2nd eye surgery (85 vs. 51%; p < 0.0001). Conclusions: The improvement in near vision without glasses was significantly more evident in ReSTOR patients, allowing the majority of them to be free of glasses.

“…To quantify the functional limitations associated with cataract, researchers have developed standardised questionnaires designed to measure the impact of impaired vision on patients' ability to perform daily activities. [1][2][3][4] Patients' responses have correlated well with patient reported trouble and satisfaction with vision before surgery and have improved significantly after cataract surgery. 1 5-7 In contrast, preoperative Snellen acuity testing does not assess the functional difficulties experienced by patients with cataract and has been documented to be poorly correlated with patient reported trouble and satisfaction with vision.…”

“…Expanded use of standardised methods of obtain-ing this information would improve the assessment of cataract patients in clinical practice and evaluation of the care they receive in different settings. 1 A recent publication indicated that the VF-14 might be able to be reduced to seven questions without compromising performance. 11 In order to further examine these findings, we sought to determine which of the individual items within the VF-14 were most responsive to cataract surgery among the population of patients enrolled in the Cataract Patient Outcomes Research Team (PORT) study and to assess the correlation between alternative combinations of these items and self reported trouble and satisfaction with vision.…”

Aims: To report the item specific responses of the VF-14 in a population of patients undergoing cataract surgery in their first eye and to determine whether or not the VF-14 can be reduced without compromising its performance as an index of cataract related visual impairment. Methods: The item specific responses to the VF-14 were analysed before (771 patients) and 4 months after (552 patients) cataract surgery in one eye to determine if the VF-14 index can be reduced without compromising its performance. Patients studied were selected from a cross sectional longitudinal study of patients undergoing cataract surgery in 72 ophthalmologist's offices located in three metropolitan regions of the United States. Results: Pairwise correlations between items in the VF-14 were all less than 0.6, indicating that no items could be removed solely on the basis of redundancy. 10 items correlated moderately with change in trouble, and 11 correlated moderately with change in satisfaction (r >0.15) at 4 months after cataract extraction. Eleven items demonstrated an effect size >0.4 at 4 months. These 11 items were either important for detecting cataract related functional disability or for quantifying the extent to which cataract impaired function. Additionally, 11 items were needed to detect adequately individuals with functional impairment. Three items (recognising people, cooking, and reading large print) were less responsive to cataract extraction and were more strongly associated with ocular comorbidities. Conclusions: While previous reports indicate that the VF-14 can be significantly shortened, our analysis only justifies removing three items. While the resulting VF-11 has properties similar to the VF-14, the limited time savings do not justify altering this already validated instrument.

“…In uveitis, not only can quality of life be affected by visual impairment but also from any associated systemic disease and the treatment the patient is taking. Few vision-related quality of life questionnaires have been validated [96], and these include NEI VFQ-14 [97], VFQ-25 [98], and VQOL [99]. A recent study using the Medical Outcomes Study 36-Item Short Form (SF-36) and the NEI VFQ-25 [100]found that patients with uveitis reported markedly poorer visual functioning and general health status than normal subjects, and patients with more severe uveitis fared worse than those with milder disease.…”

Uveitis (intraocular inflammation) is a potentially blinding group of, probably autoimmune, conditions predominantly occurring in the working age group. Although the aetiology is unknown in most cases, many patients have an associated underlying systemic disease. Central vision loss, in the form of cystoid macular oedema, is the commonest type of visual impairment. Although historical incidence and prevalence data exists, little is known about the degree of vision loss experienced, and the social and financial consequences of having temporary or permanent visual impairment in this age group. The literature is also full of uncontrolled studies and case reports of different modalities of drug therapy for uveitis. This article attempts to raise the awareness of uveitis as an important sight-threatening group of conditions by highlighting the paucity of evidence-based data on epidemiological, quality of life, socioeconomic, and therapeutic aspects.
