This commentary describes steps in ocular reconstruction surgery following ocular globe injuries in both the anterior and posterior segment causing corneal opacity and aphakia. The authors propose to reorder the sequence of surgical manoeuvres during pars plana vitrectomy combined with keratoplasty and aphakia treatment without capsular support and highlight the advantages in the choice of the intraocular lens to implant. A mental outline of all surgical manoeuvres, being aware of the complications that can arise during surgery and knowing the long-term benefits of making more careful choices, can make this surgery more effective and safer.

Review
BACKGROUND
To assess the constants and formula for aphakia correction with iris-claw IOLs to achieve the best refractive status in cases of late in-the-bag IOL complex dislocation.
METHODS
A literature search was performed. The following data were obtained: Iris-claw IOL model, Iridal or retroiridal enclavation, A-constant, ultrasound or optical biometry, formula employed and refractive outcomes. Acceptable emmetropia was considered if the resulting spherical equivalent (SE) was within ±1.00 D.
RESULTS
The majority of the studies used SRK/T formula (66.6%). The 88.9% of the reports obtained a SE within ±1.00 D. Using A-115 for ultrasound biometry and A-115.7 for optical biometry and SRK/T formula, the emmetropia (±1.00 D) of SE, was able to get near 100% of reported cases over the pupil implantation. However, the emmetropia decreased to 80% when the enclavation is retropupilar using the same formula. The A-constant can vary from 116.7 to 117.5 for retropupilar enclavation.
CONCLUSIONS
Using A-115 for ultrasound biometry and A-115.7 for optical biometry and SRK/T formula, ±1.00 D of SE, is able to get near 100% of cases. Nevertheless, ±1.00 D of SE decreased to 80% of the cases when the enclavation is retropupilar.

Review
Congenital cataract is among the main causes of treatable vision loss in childhood. The first weeks and months of life are a critical time for the development of vision. Therefore, early cataract surgery and effective multifaceted treatment of the resulting aphakia in the early stages of life are of great value for the management of vision development. Among the treatment models, contact lenses (CL) have an important place in infancy and early childhood up to the age of 2 years. Although good visual gains were not considered very likely, especially in unilateral aphakia, important steps have been taken in the treatment of pediatric aphakia thanks to the surgical techniques developed over time and the increasing experience with optical correction systems, especially CLs. This review examines current developments in the types of CL used in pediatric aphakia, their application features, comparison with other optical systems, the features of amblyopia treatment in the presence of CL, and the results obtained with family compliance to CL wear and occlusion therapy in the light of existing studies.

Review
The visual outcomes for infants 18 months or younger with cataracts have improved dramatically over the past couple of decades. Earlier detection of infantile cataract and prompt surgical removal-with subsequent visual rehabilitation with contact lenses-mean that these patients now have a much better visual prognosis. Advances in contact lens technology have led to a significantly higher success rate with contact lenses and this has been a major factor in improving the visual outcomes for aphakic infants. This review outlines the contact lens management of infantile cataract, including a detailed analysis of the various contact lens options available and a discussion regarding the important factors that can cause issues with contact lens wear and affect the overall visual rehabilitation of the infant.

Indian Journal of Ophthalmology Apr 2022To carry out a prospective study to analyze the incidence and various preoperative, intraoperative, and postoperative risk factors for the development of PPKG.
PURPOSE
To carry out a prospective study to analyze the incidence and various preoperative, intraoperative, and postoperative risk factors for the development of PPKG.
METHODS
A total of 207 patients were analyzed prospectively, who were operated for penetrating keratoplasty (PK) in a tertiary eye care hospital between the time period of August 1, 2017 and February 28, 2018 and were followed up till the sixth month. Each patient was analyzed at every visit to determine the factors responsible for post-keratoplasty glaucoma.
RESULTS
Out of 207 eyes, post-PK glaucoma developed in 84 cases, which yielded an incidence of 41%. Incidence of PPKG (Post PK glaucoma) in various conditions was as follows: in repeat PK 62%, in perforated corneal ulcer 33%, in nonperforated corneal ulcer 29%, in corneal scar including adherent leukoma 37.2%, and in pseudophakic bullous keratopathy and aphakic bullous keratopathy, 14% and 80%, respectively. In age- and sex-adjusted multivariate analysis, the significant risk factors were age (P-value- 0.006), presence of PAS (P-value 0.001), and fellow eye glaucoma (P-value 0.04). Aphakia and combined surgery were not found to be significant.
CONCLUSION
Our study recommends a meticulous examination of the fellow eye to assess the presence of glaucoma as it can increase the suspicion of glaucoma in the eye to be operated. The presence of PAS and age are important risk factors for developing PPKG. The risk of developing PPKG increases exponentially as the number of risk factors increases, but the presence of more than three risk factors does not add to the development of PPKG.

To study the risk factors in the development of glaucoma following penetrating keratoplasty, we retrospectively analysed 190 eyes of 185 consecutive patients who had undergone surgery during 1990. The donor button was larger by 0.2 mm and 0.5 mm in phakia and aphakia/pseudophakia patients, respectively. Over a mean follow-up period of 14.5 months, 52 of the 190 eyes (27.4%) either developed glaucoma de novo or had worsening of preexisting glaucoma. Of these 52 eyes, 38 were managed medically and 14 required surgery. From our study, aphakia (37%), pseudophakia (24%), preexisting glaucoma (81.8%), and regrafting (43.18%) were found to be the significant risk factors in the development of glaucoma following penetrating keratoplasty.
