NCT ID: NCT05123014 Active, not recruiting - Clinical trials for Adenoviral Keratoconjunctivitis

Lenticule Implantation and Autologous Serum New Approach in Treatment of Adenoviral Keratitis Disease

Start date: February 1, 2018
Phase: N/A
Study type: Interventional

Adenoviral keratitis(caused by adenovirus) is one of the most frequently diagnosed eye diseases. Most of these infections have symptoms like (Ocular itchiness and irritation, chemosis (conjunctival edema),photophobia, epiphora, foreign body sensation, epithelial keratitis etc.Adenoviral subepithelial infiltration is one of the most difficult complication to treat. Our purpose is to evaluate corneal transparency, recurrence, and visual acuity in patients with adenoviral subepithelial infiltration by first removing the infiltrative stroma with a smile and implanting the same volume of fresh lenticule in the prepared stromal pocket.

NCT ID: NCT04987060 Active, not recruiting - Clinical trials for Irregular Astigmatism

Intrastromal Fresh Human Corneal Lenticule Implantation Using Smile Surgery for Treatment of Irregular Corneal Astigmatism After Penetrating Keratoplasty (New Approach)

Start date: March 1, 2017
Phase: N/A
Study type: Interventional

The aim of the study is to present the effect of implanting intrastromal fresh corneal lenticule by SMILE surgery as a new method-approach to correct the corneal shape on purpose to reduce irregular astigmatism and increasing visual acuity after penetrating keratoplasty.

NCT ID: NCT04692012 Active, not recruiting - Myopia Clinical Trials

Treatment of Residual Hypermetropic Refraction on Pseudophakic Patients Using Allogenic Fresh Myopic Lenticule

ReLex-Smile
Start date: April 1, 2018
Phase: N/A
Study type: Interventional

The residual hypermetropic refraction on pseudophakic(Trifocal IOL) patients is difficult to treat surgically. In addition, there are not many suitable options to offer such patients presenting with this condition. Two current common surgeries to treat residual hyperopic refraction are refractive lens exchange (RLE) and excimer laser ablation (LASIK or PRK). Laser procedures: Photorefractive keratectomy (PRK); Laser assisted in situ keratomileusis (LASIK); Risks of LASIK include abnormalities of the corneal flap, epithelial ingrowth, corneal ectasia, refractive surprises, irregular astigmatism, decentration, visual aberrations, a loss of BCVA, infectious keratitis, symptoms, and diffuse lamellar keratitis. Refractive lens exchange (RLE); The risks of RLE are similar to those of cataract surgery and include endophthalmitis, a loss of accommodation, vitreous loss with posterior capsular rupture, and retinal detachment. The method used at the EYE Hospital Pristina using fresh lenticule implantation by ReLex-SMILE is safe and effective method, since there is no flap this prevents invasive damage to the anterior surface of the cornea contrary to the LASIK where flap is present posing risk for epithelial ingrowth. Before SMILE,YAG-laser capsulotomy should be performed on all patients, regardless of posterior capsule ossification, in pseudophakic patients with residual refraction. When the YAG-laser is applied after the SMILE,there will be a diopter change.

NCT ID: NCT04616144 Active, not recruiting - Hyperopia Clinical Trials

Fresh Corneal Lenticule Implantation in Hyperopic Patients With High Astigmatism

Start date: May 1, 2019
Phase: N/A
Study type: Interventional

The refractive combination of high hyperopia with high astigmatism is difficult to treat surgically. In addition, there are not many suitable options to offer such patients presenting with this condition. The method used at the EYE Hospital Pristina using fresh lenticule implantation by ReLex-SMILE is safe and effective method. Fresh Corneal Implantation is a safe treatment for hyperopia with high astigmatism comparing with refractive IOL implantation (loss of accommodation, endophthalmitis). Its primary objective is to increase visual acuity, accommodation process, patient satisfaction which makes patient to enjoy a happier life. We believe this study will be the future of refractive surgery for treating high hyperopia.

NCT ID: NCT04594512 Active, not recruiting - Keratoconus Clinical Trials

Fresh Corneal Lenticule Implantation and Autologous Serum - Case Report

Start date: May 8, 2019
Phase: N/A
Study type: Interventional

The aim of our study is to investigate the feasibility and the effect of fresh lenticule implantation as allogenic graft that will be taken from myopic patients to implant in patients with keratoconus disease using VisuMax Femtosescond laser- Smile module surgery with primary objective to increase central corneal thickness and secondary to improve visual acuity and reduces K-values and to show the autologous serum drop improve the recovery of patients with mild dry eye in keratoconus disease.
