Abstract PurposeTo determine the two-year results of small incision lenticule extraction (SMILE) for correcting post-keratoplasty myopia and myopic astigmatism.MethodsIn this case-series study, 10 eyes of 10 patients with a 6-10-year history of successful deep lamellar keratoplasty (DALK) underwent SMILE using VisuMax laser platform. Ophthalmologic examinations and visual acuity and refraction measurement were done pre- and 1, 3, 6, 12, and 24 months postoperatively. Pentacam and Sirius imaging was done in the first and last follow-up session.ResultsThe mean age of the patients was 39.60±7.86 years. Six subjects were male. After two years, uncorrected distance visual acuity did not change in one eye and improved 1-6 lines in other eyes. Corrected distance visual acuity decreased in one eye, did not change in four eyes, and improved 1-8 lines in other eyes. The mean decrease of spherical equivalent, spherical error, and cylinder power was 1.92±1.96 diopter (D) (P=0.013), 0.70±3.05D (P=0.213), and 2.42±2.91D (P=0.024), respectively. The vector mean target induced astigmatism, surgical induced astigmatism, and difference vector was 1.30D@44˚, 1.11D@24˚, and 0.86D@73˚, respectively. Two years after surgery, vertical coma, horizontal coma, and spherical aberration increased by 0.44±0.51, 0.23±0.32, and 0.02±0.16µm respectively (all P>0.05) while trefoil reduced by 0.29±0.75µm (P=0.428).ConclusionSMILE is a successful procedure for reducing refraction and astigmatism after DALK in patients with moderate myopia and moderate to severe astigmatism and improves the visual acuity in these patients. Axis rotation during surgery may result in under-correction of astigmatism. Refinement of SMILE treatment nomogram for post-DALK cases seems necessary.

We assessed the outcomes of the use of anterior chamber foldable lens for unilateral aphakia correction at the University Teaching Hospital of Yaounde. In this retrospective, non-comparative, consecutive case series study, we reviewed the records of patients who underwent an operation for aphakia correction by the means of injection of an angular supported foldable lens between January 2009 and December 2011 in the University Teaching Hospital Yaounde. Student's paired t-test was carried out to compare preoperative and postoperative visual acuity (VA) and intraocular pressure (TOP). P-values less than 0.05 were considered statistically significant. Twenty-one patients were included in the study; twelve were male (57.1%) and nine were female (42.9%). The mean age was 55.38 ± 17.67 years (range 9–75 years). The mean follow-up duration was 5.95 ± 3.14 months (range 2–12 months). The mean logMAR visual acuity was 1.26 ± 0.46 pre-operatively and 0.78 ± 0.57 post-operatively ( P = 0.003). The change in intraocular pressure was not statistically significant. Complications included intraocular hypertension (over 21 mmHg) in 3 patients (14.3%) and macular edema, pupillar ovalization, and retinal detachment in one patient each. The results indicate that injection of an angular support foldable lens in the anterior chamber is a useful technique for the correction of aphakia in eyes without capsular support. More extended follow-up, however, and a larger series of patients are needed to ascertain the effectiveness and safety of this procedure.

Objective: To report a rare case of intraocular lens (ACIOL) opacification in the anterior chamber in an adolescent and to discuss the possible mechanism of its occurrence and the ways of its prevention. Case: A 16-year-old male underwent cataract surgery for developmental cataract with placement of a foldable posterior chamber IOL in the anterior chamber. There was subsequent opacification of the IOL, which was replaced by a scleral fixated posterior chamber intraocular lens. The post-operative visual acuity improved to 6/18. Conclusion: The posterior chamber IOL implanted in the anterior chamber can get opacified possibly due to postoperative intraocular inflammation.

The objective of this case report was to present the development of implantation cyst following the perforating corneal injury, the problems related to the treatment, including total surgical excision of the cyst, the secondary cataract extraction, iridoplasty and the artificial intraocular lens reposition. A patient first presented with perforating corneal injury inflicted by a piece of wood, with the iris prolapse. Primary wound management, reposition of prolapsed iris and corneal sutures were performed four days after the injury. Eight months later, the patient was rehospitalized due to an implantation iris cyst and traumatic cataract. The cyst was excised, the extracapsular cataract extraction was done and the anterior chamber lens was implanted. Postoperative visual acuity was normal. Three years later, the patient presented for a follow-up examination, with the cyst filled up again, occupying two thirds of the anterior chamber. This time, the cyst was completely excised, all fibrous remnants of the secondary cataract were removed, and the iridoplasty was necessary due to large iris coloboma. Reposition of the anterior chamber lens was carried out. Histological examination revealed an implantation iris cyst covered by multilayered squamous epithelium. Normal visual acuity was achieved. The patient has been followed-up for six months uneventfully. Management of perforating corneal wound with iris prolapse may lead to development of an implantation iris cyst. Puncture of the cyst as well as incomplete excision will not solve the problem. Complete surgical removal of the iris cyst is the treatment of choice.

Abstract Purpose To evaluate early intraocular pressure (IOP) changes following different keratoplasty techniques and to investigate the relationship between corneal thickness (CT), keratometry values, anterior chamber depth (ACD) and IOP changes. Methods We included patients who underwent penetrating keratoplasty (PK), deep anterior lamellar keratoplasty (DALK) and Descemet membrane endothelial keratoplasty (DMEK). ACD, CT, and keratometry measurements were repeated postoperatively at hour 24, week 1, and month 1. IOP measurements were repeated at postoperative hours 6 and 24, week 1, and month 1 by Tono-Pen XL. Results Twenty-two patients underwent PK, 12 patients underwent DALK, and 19 patients underwent DMEK. The difference between the IOP preoperatively and 6 hours postoperatively and between the IOP preoperatively and 24 hours postoperatively were statistically significant in the three types of surgery (p < 0.05 for each). The difference between preoperative and postoperative week 1 IOP was statistically significant only in the PK group (p = 0.023). When the IOP was compared between the three types of surgeries, the IOP at postoperative week 1 in the PK group was significantly higher than the DALK and DMEK groups (p = 0.021). There was no correlation between ACD, corneal thickness, K values, and IOP in any group. Conclusion IOP may increase in all types of keratoplasty during the first hours after surgery, but PK has a risk of high IOP longer in the early postoperative period. PK patients should be followed more carefully during postoperative week 1 to check for an increase in IOP.

Anterior Lamellar Keratoplasty

Purpose: To compare the visual outcome of femtosecond laser-assisted anterior keratoplasty (FSALK) and microkeratome-assisted anterior lamellar keratoplasty (MALK) in anterior corneal dystrophy.  Methods: retrospective comparative chart review of 7 eyes that underwent FSALK and 7 eyes that underwent MALK. The primary outcome was the visual outcome of both procedures. The secondary outcome was the recurrence of the corneal dystrophies.Results: Mean follow-up time was 30±14(7-51) months for the FSALK group and 127±28(80-127) months for the MALK group. In the FSALK group the preoperative best spectacle-corrected visual acuity (BSCVA) improved from 20/63 to 20/25 at 36 months. In the MALK group there was 1 eye with documented BSCVA over 36 months follow-up; it improved from 20/160 preoperatively to 20/32 at 36 months. Uncorrected visual acuity (UCVA) at 36 months improved from 20/100 preoperatively to 20/63 in the FSALK group and from 20/200 preoperatively to 20/63 in the MALK group. Five eyes with Reis-Bucklers showed a clinical recurrence at a mean of 142±13(125-152) months. Two eyes with granular dystrophy showed a clinical recurrence at 23 and 80 months of follow-up. One eye in the MALK group had epithelial ingrowth. One eye in the FSALK group with compromised ocular surface due to 2 previous penetrating keratoplasty, suffered bacterial keratitis that ended up with corneal scarring. Conclusion: Both procedures improve visual outcome for anterior corneal dystrophy. FSALK has theoretical advantages over MALK; however, larger prospective studies are needed to prove this.
