Purpose:Visual rehabilitation in aphakia can be performed using several modalities. However, these modalities could be either technically difficult or expensive. Herein, we developed a scleral tuck lens to provide a simple and cost-effective solution for aphakia and compared its outcome with standard methods.Methods:A specially designed posterior chamber self-sustaining lens was implanted in patients with aphakia without capsular support because of different primary etiologies. The visual outcomes, as well as intraoperative and postoperative complications, were examined. The data were retrieved from electronic medical records, and visual outcome and complication rates were compared. The outcomes were also compared according to the etiology and age groups (pediatric and adults).Results:We found significant improvement in preoperative and postoperative visual outcome. We did not find any significant difference in visual outcome amongst suture-supported scleral fixated lens with scleral tuck lens.Conclusion:Satisfactory visual outcomes were noted with minimal complications; and comparable with gold standard suture fixated lens, however long-term follow-up is required. 相似文献

Futility has been a contentious topic in medicine for several decades. Surgery in critical or end-of-life situations often raises difficult questions about futility. In this article, we discuss the definition of futility, methods for resolving futility disputes, and some ways to reframe the futility debate to a more fruitful discussion about the goals of care, better communication between surgeon and patient/surrogate, and palliative surgical care. Many definitions of futile therapy have been discussed. The most controversial of these is “qualitative futility” which describes a situation in which the treatment provided is likely to result in an unacceptable quality of life. This is an area of continued controversy because it has been impossible to identify universally held beliefs about acceptable quality of life. Many authors have described methods for resolving futility disputes, including community standards and legalistic multi-step due process protocols. Others, however, have abandoned the concept of futility altogether as an unhelpful term. Reframing the issue of futility as one of inadequate physician–patient communication, these authors have advocated for methods of improving communication and strengthening the patient–physician relationship. Finally, we discuss the utilization of consultants who may be of use in resolving futility disputes: ethics committees, palliative care specialists, pastoral care teams, and dedicated patient advocates. Involving these specialists in a futility conflict can help improve communication and provide invaluable assistance in arriving at the appropriate treatment decision. 相似文献
