Cornea Clinical Trial - ASSESSMENT OF INTRA-OPERATIVE AND EARLY

Status Not yet recruiting

Clinical Trial Summary

To discuss the prevalence of intra-operative and early post-operative complications of LASIK among individuals who underwent LASIK procedure and review the symptoms, findings, and management options.

Clinical Trial Description

In recent years, a number of possible surgical procedures in ophthalmology has offered patients an alternative to spectacles or contact lenses. Several laser and non-laser refractive surgical procedures have been used to modify the shape of the cornea and correct myopia, hyperopia, astigmatism, and presbyopia. Introduction of the excimer laser to reshape the cornea has resulted in remarkable developments in the correction of refractive errors. Combined with other advanced ophthalmic instruments, laser refractive eye surgery has resulted in a substantial increase in the safety, efficacy, and predictability of surgical outcomes.

Refractive surgery has enabled individuals to enter occupations they were previously precluded from due to their vision.Laser in situ keratomileusis (LASIK) surgery is one of the most common surgeries performed worldwide to correct refractive errors and reduce dependence on eyeglasses or contact lenses. In addition, patient satisfaction following LASIK is commonly reported as high and studies of the visual and refractive outcome of LASIK for the treatment of myopia and astigmatism have reported great success.

LASIK, compared to photorefractive keratectomy (PRK), has low postoperative discomfort, early visual rehabilitation and decreased postoperative haze. LASIK involves an additional procedure of creating a corneal flap. This may result in complications related to the flap, interface and underlying stromal bed. The common flap-related complications include thin flap, button holing, free caps, flap dislocation, torn flap, incomplete cut, and flap striae. The interface complications of diffuse lamellar keratitis, epithelial ingrowth and microbial keratitis are potentially sight threatening. After LASIK, there is a long period of sensory denervation leading to the complication of dry eyes. The refractive complications include under-correction, over-correction, regression, irregular astigmatism, and visual aberrations. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
