Abstract Background To evaluate the long-term results of therapeutic keratoplasty for a consecutive case series of corneal perforation.Methods The cases comprised 41 eyes (41 patients) that underwent therapeutic keratoplasty using cryopreserved donor grafts at the Keio University Hospital between January 2012 and December 2016. The eyes were evaluated regarding the cause of corneal perforation, surgical procedure, size of the perforation, presence of anterior chamber collapse, visual prognosis, and complications.Results The major causative diseases included herpetic keratitis (n = 11), bacterial and fungal corneal ulcer (n = 4), Mooren’s ulcer (n = 5), severe dry eye (n = 4), and neuroparalytic keratitis (n = 4). Penetrating keratoplasty was performed in 28 eyes (68.2%), lamellar keratoplasty in 8 eyes (19.5%), and keratoepithelioplasty in 5 eyes (12.2%).

Visual Results

One of the leading causes of blindness is corneal disorder. By keratoplasty we can restore vision of those patients to some extent and many surgeons are performing keratoplasty on vascularised cornea. Present study was done to evaluate its outcome. Patients (5-70 yrs) were recruited from eye ward of Dhaka Medical College Hospital from January, 2007 to December, 2007. Patients were selected on some criteria. Total 33 cases were evaluated before and after operation. This study was carried out to know pattern of blindness and to obtain the causes of corneal vascularisation and results of keratoplasty on these patients. Among 2 types of grafting all our patients were undergone penetrating keratoplasty. Male predominance (57.50) was marked as male are more prone to corneal diseases and trauma. Considering age group nobody is immune from corneal disease but children and young persons are more vulnerable. Socio-economic status of our maximum patients are middle-class or poor class. We got a rough idea about the causes leading to vascularisation of cornea. Amongst them; trauma, corneal ulcer, chemical injury and under nutrition are noted in our study. Out of 33 healthy grafts, visual improvement occurred in 24 cases. Visual results of grafting on vascularised corneas are variable. Our study concludes that trauma and corneal ulcer are the leading causes of corneal opacity which need penetrating keratoplasty. Whatever the cause of corneal vascularisation, prognosis of keratoplasty on such cases is not disappointing. Rather keratoplasty done on early notified corneal opacity with superficial vascularisation gives satisfactory results.Medicine Today 2017 Vol.29(1): 23-25

Therapeutic Penetrating Keratoplasty

BACKGROUND Corneal blindness has been a significant visual disability in developing countries like India. Corneal ulcer contributes mainly as the leading cause for monocular blindness. Considering the common condition, the studies and literature have been surprisingly less when it comes to corneal ulcer and their management. But with the advent of therapeutic penetrating keratoplasty (TPK), the scenario and prevalence of corneal blindness can be reduced. Hence this study was done to know the importance of therapeutic penetrating keratoplasty in case of non-healing infective and perforated corneal ulcers. The objectives were to assess the clinical outcome in a non-healing and perforated corneal ulcer, reduction in symptoms and signs of infection, anatomical or structural integrity of the globe and also evaluate the visual outcome following therapeutic penetrating keratoplasty. METHODS Data were obtained from 30 patients operated at our institute for therapeutic penetrating keratoplasty. Patients with less than one year of follow up, paediatric cases, PL negative cases were excluded. The outcome was assessed based on maintenance of structural integrity, reduction in infective load, improvement in visual acuity and graft survival and its correlation with corneal vascularisation, previously failed grafts, donor tissue quality, graft size and type of surgery. RESULTS Structural integrity was maintained in 93.3 % of the cases, reduction of infective load in 90 % of cases and optically clear grafts in 46.7 % of cases and vision was better than 6/60 in 30 % of cases. CONCLUSIONS The study proved that in the case of non-healing and perforated corneal ulcers, therapeutic penetrating keratoplasty had a good prognosis in reducing infective load, maintaining structural integrity without which eye could have been lost.

Purpose:  To study the effect of intrastromal Voriconazole for treatment of resistant fungal keratitis in a tertiary care eye hospital in Lahore, Pakistan. Study Design:  Experimental interventional study. Place and Duration of Study:  Avicenna Medical College Hospital, Lahore, from July 2017 to July 2019. Methods:  Sixty four patients were selected. All patients with fugal keratitis were included. The patients with previous corneal scar, mature cataract, endophthalmitis, Panophthalmitis, scleral involvement, impending or frank corneal perforation and uncontrolled diabetic patientswere excluded.Corneal scrapings of all patients were sent for 10% KOH staining. All patients were given intrastromal Voriconazole at 3 to 4 sites in divided doses in one ml syringe with 27-guage needle. Injection was repeated on 4th and 8th day. It was combined by topical antifungal and antibiotic eye drops six hourly. Patients were followed at day two, five, nine, three weeks and at 3 months. Results:  There were 55 males and 9 females. Average size of ulcer was 6.4mm ranging from 5.5mm ± 1.8mm. Fifty six (88%) patient showed improvement while eight (12%) patients ended up in melting of cornea which was managed with tectonic corneal graft. In three (5%) patients penetrating Keratoplasty was done. Conjunctival congestion and ocular pain improved significantly one week after third dose but final visual acuity was not significantly improved due to scarring. Conclusion:  The intrastromal corneal voriconazole is an effective treatment for fungal keratitis in term of healing corneal ulcer, control of infection and saving of eye from corneal perforation and permanent blindness. Key Words:  Voriconazole, Fungal keratitis, Penetrating Keratoplasty.
