Abstract
The response of living tissues to the surgical trauma is associated with varying degrees of tissue repair and involves two distinct processes including replacement and regeneration. Replacement results in scar tissue formation instead of restoration of the normal architecture. However, regeneration leads to restoration of the original architecture leaving no sign of injury. Anti-proliferative agents are used to inhibit tissue responses to surgical trauma. Among them mitomycin- C and 5- FU had gained increasing applications in ophthalmic surgeries, including filtering glaucoma surgeries, laser vision correction with excimer laser by ablative surface refractive surgery, reconstructive surgeries for ocular surface disorders and removal of neoplastic tissues and secondary operations on nasolacrimal ducts. In this review article, the various aspects of applications of these agents including their mechanism of action, function, mode of application and complications in different ophthalmology fields are discussed.

Abstract
Eyes and the vision system allow the human being to receive information from the environment to the extent that 90% of the man’s information is acquired through observation, thus health and correct function of this organ have always been important.
Diseases threatening vision such as Acute Macular Degeneration and Diabetic Retinopathy deprive millions of people of seeing every year while access to proper cures can prevent many ocular damages.
Despite scientific progress in the medical fields over the recent decades there still exist many challenges in the field of ophthalmology and ocular diseases.
As for ocular treatments, major challenges stem from pharmaceutical weaknesses, in other words in spite of access to the suitable drugs for ocular complications we have not yet succeeded to achieve an appropriate method to apply these drugs. By appropriate application of drugs we may deliver the active pharmaceutical ingredient to the target organ with the least side-effect, the most benefit and the highest level of patient compliance.
Incapability of effective delivery of drug to the eye arises from the special physiology and anatomy of this organ. The static barriers such as Blood-Aqueous and Blood-Retinal and dynamic barriers such as conjunctival blood circulation and lymphatic clearance will reduce the bioavailability of ocular drugs. Overcoming the above-mentioned weaknesses requires a complete knowledge of the eye characteristics as well as acquaintance with novel drug delivery system. When speaking of drug delivery system (DDS) it means employing a two-part structure consist of active pharmaceutical ingredient (API) and carrier that in fact characteristics of formulated DDS will determine by the carrier. We may hope that by applying and designing modern pharmaceutical systems that mainly take advantage of nanoparticles we would be able to overcome many challenges of ocular drug delivery.
The present study is aimed at reviewing the eye structure, challenges faced by ocular drug delivery, familiarity with nanotechnology and approaches of this science in the area of ophthalmology as well as mechanisms of designing a local system for effective drug delivery to the eye tissue.

Abstract
Background: Although significant advances have been made in scientific and medical technology, but the rate of medical complaints has also risen. The purpose of this study was to investigate the effect of handling of medical malpractice cases in the hospital complaints committee on the reduction of patient complaints to law enforcement authorities.
Methods: In this descriptive study, patients complained about ophthalmology from April 2005 to December 2005 at Farabi Hospital, Tehran, were evaluated. The complainant's patients, if confirmed by the trusted doctors, were invited to complaints committee, and the subject of the complaint was examined and tried to obtain patient satisfaction.
Results: A total of 87 patients complained to ophthalmologists completed a complaint form 71 (81.7%) of the cases were male. Statistically, the number of complaints was significantly lower in those with lower education (P=0.02). The prevalence of primary disease, 52 cases (59.8%) was cataract and 14 cases (16%) due to refractive errors and refractory surgery. In the examination of complaints by trusted doctors in the hospital, 11 cases of ophthalmologic error were identified, with a mantle rate of 12.6%, and the cases were reviewed by the complaints committee. Of the cases of complained that confirmed by the committee, only one person sued the law enforcement, which represented 9% of the defaulted item. These statistics showed a significant decline compared to the past year at the same center, and the percentage of defaults to law enforcement was 37.5% (P<0.05).
Conclusion: Establishing committees to handle complaints of ophthalmologic failures in hospitals and providing a clear and honest atmosphere to hear the subject of complaints by patients and their companions, and then trying to get patients' satisfaction and helping them continue their treatment can lead to reduced complaints of patients to the authorities Legal, like forensics medicine department and medical council.

Abstract
Background: Today, despite the efforts of the medical community and health staff, the rate of dissatisfaction and complaints among patients is increasing and this highlights the importance of evaluating its related factors. The aim of this study was to analytically investigate complaints against ophthalmologists which were referred to the Legal Medicine Organization of Iran in Tehran during 2017-2019.
Methods: In this cross-sectional (analytical-descriptive) study, the demographic data of patients and physicians including age, gender, marital status and academic degree, type of treatment measures leading to complaints, last decision of the medical commission, characteristics of protesting of patients and vote of revision commissions for all the complaints of ophthalmology were recorded and analyzed.
Results: During 3 years, 176 complaints were recorded in the field of ophthalmology. Of these, 90(51.1%) complaints were from medical interventions which took place in university or government hospitals and clinics. Also, 27(15.3%) cases of malpractice were reported, among which negligent was the most common type, with 22 cases (81.5%). The highest number of complaints was for cataract surgery and the most frequent treatments with malpractice of the physicians were cornea transplantation. Although the most protests to the first decision were from the patients, the effectiveness of physicians’ protest was significantly higher (P<0.001).

Conclusion: Nowadays, with advances in treatment methods and technologies in ophthalmology and enhancement in the knowledge of patients about their rights, their expectations from medical staff have changed. The findings of the present study suggest that due to the rise in the number of complaints in ophthalmological treatment while a decrease in malpractice rate, applying intervention actions such as good communication between physicians and patients and patient’s right perception of treatment and possible side effects can lead to less number of complaints. In addition, due to different opinions in consecutive commissions, utilizing a single approach based on new information and evidence seems necessary.
