Purpose: Keratoconus (KCN) is one of the most common indications of corneal transplantation in Iran. This study was conducted to determine the outcomes of penetrating keratoplasty (PK) for KCN in patients operated in a private practice setting from 1994 to 2001. Methods: This longitudinal retrospective study included 164 eyes of 164 patients. Variables included preoperative keratometry, trephination and suturing techniques, donor-recipient disparity, surgical complications, immunologic… Expand
Penetrating keratoplasty for keratoconus: visual and graft survival outcomes.
TLDR
Performing PKP in eyes with keratoconus is associated with good visual results and an excellent graft outcome and Kaplan-Meier analysis revealed that the probabilities of graft survival were 99.8% at 1 year and 97.6% at 5 years after transplantation. Expand
Penetrating Keratoplasty for Keratoconus in Vietnamese Patients
TLDR
PK is an effective procedure with high rate of graft survival for keratoconus patients, however, patients should be aware of the necessary of optical correction to gain the best VA after surgery. Expand
Outcomes of Penetrating Keratoplasty and Deep Anterior Lamellar Keratoplasty for Keratoconus in a University Teaching Hospital
TLDR
Visual and refractive outcomes in PK and DALK for keratoconus are comparable, whereas CSFs were lower in DALK in comparison to PK and graft failure was higher in Dalk. Expand
Outcomes of Deep Anterior Lamellar Keratoplasty in Patients with Keratoconus Using the Big-bubble Technique
TLDR
DALK using the big-bubble technique appears to be an effective procedure for patients with keratoconus and in the case of extensive intraoperative DM perforation or postoperative complications, PK could be done without any limitation. Expand
Deep Anterior Lamellar Keratoplasty versus Penetrating Keratoplasty for Keratoconus
TLDR
DALK may be considered as an effective alternative to PK in patients with keratoconus and there was no significant difference between the study groups in terms of CSF, total aberrations and HOAs. Expand

AIM: To investigate the long -term results of penetrating keratoplasty (PK) in patients with keratoconus (KC) and to evaluate factors that might influence the final visual outcome. ·METHODS: WeExpand
Effect of Keratoconus Severity on Clinical Outcomes After Deep Anterior Lamellar Keratoplasty.
TLDR
DALK is a safe and effective procedure for the treatment of all stages of keratoconus and this technique of corneal transplantation is more effective in eyes with severe ker atoconus compared with those with moderate keratconus. Expand
A Retrospective Contralateral Study Comparing Deep Anterior Lamellar Keratoplasty With Penetrating Keratoplasty
TLDR
Over the 2-year follow-up after DALK, EC loss was significantly lower, whereas the visual outcomes were comparable with those of the PK-operated eyes, suggesting DALK is an effective alternative surgical procedure for corneal stromal pathologies. Expand
DEEP ANTERIOR LAMELLAR KERATOPLASTY USING THE BIG-BUBBLE TECHNIQUE
TLDR
DALK is a valuable and successful alternative to PKP in patients with keratoconus with poor spectacle-corrected visual acuity and/or contact lens intolerance and is associated with good recovery because the endothelium is not involved. Expand
Deep Anterior Lamellar Keratoplasty Versus Penetrating Keratoplasty for Keratoconus: A Clinical Trial
TLDR
DALK is an effective alternative surgical procedure for patients with keratoconus; the outcomes are comparable to PK in terms of refractive errors, BCVA, CSF, and HOAs. Expand

Penetrating keratoplasty for keratoconus: visual outcome and success.
TLDR
Graft survival was excellent and a corrected visual acuity of 20/40 or better was obtained in 86% of eyes, and astigmatism could not be predicted from preoperative factors. Expand
Corneal transplant for keratoconus: Results in early and late disease
TLDR
The improved results, low complication rate, and postoperative enhancement management indicate that corneal transplantation is a viable option early in the clinical course of keratoconus. Expand

PURPOSE To study the long-term complications of penetrating keratoplasty (PKP) to evaluate current recommendations to patients with keratoconus. SETTING John Moran Eye Center, University of Utah,Expand
Impact of Preoperative Corneal Curvature on the Outcome of Penetrating Keratoplasty in Keratoconus
TLDR
With laser trephination and a double running suture, the refractive and visual outcome of PK for keratoconus seems to be independent on the patient's preoperative corneal curvature or irregularity, and the policy of not performing PK in ker atoconus eyes before the patient becomes contact lens intolerant is well supported. Expand
The results of penetrating keratoplasty for keratoconus.
TLDR
The most serious complication seen in the group of patients was a retrocorneal fibrous membrane that developed in one patient. Expand
Refractive surgery for graft-induced astigmatism after penetrating keratoplasty for keratoconus.
TLDR
Of a series of 201 corneal transplants for keratoconus over a 20-year period, 42 grafts required further surgery because of intolerable astigmatism, and Relaxing incisions offer the prospect of more rapid visual rehabilitation than compressive resuturing. Expand
Evaluation of penetrating keratoplasty in keratoconus
Abstract. Penetrating keratoplasty was done in 104 cases with keratoconus. The donor material were preserved either as a whole eye in moist chamber at 4°C, or as a corneoscleral segment in MK‐mediumExpand
Penetrating keratoplasty for keratoconus: complications and long-term success.
TLDR
A series of 100 penetrating keratoplasties for keratoconus performed between 1968 abd 1986 were reviewed for long-term results and no relationship was found between donor age and long- term graft clarity. Expand
Prediction of refractive outcome in penetrating keratoplasty for keratoconus.
TLDR
A straight-line relationship between vitreous cavity length and spherical equivalent for a one-surgeon series using the same technique throughout is found and the final spherical equivalent following PK for keratoconus can be predicted. Expand
Factors Associated With the Need for Penetrating Keratoplasty in Keratoconus
TLDR
The presence of scarring and high keratometry values at initial presentation may help to predict the likelihood of requiring a PK and may aid in patient counseling. Expand
