Refractive surgery cases affected by complications are the focus of this book, and in it, four editors show in practical terms how such complications can be managed. They provide the important knowledge and essential details necessary to achieve successful outcomes.
They make mention of a book published in 2007 entitled Complicated Cases in Refractive Surgery. This was well received and translated into many languages including Chinese. They offered state-of-the-art pathogenesis and shared their knowledge of how to manage complications in refractive surgery in that book.
You may or may not be familiar with the didactic technique of arriving at solutions to problems. An example where this technique is used is the problem resolution method. This practical hands-on method is currently being used in teaching medicine. It originated about 2,400 years ago with Hippocrates on the island of Kos.
In this book Drs. Abbouda, Alio, Aswad, and Azar present 101 cases. Some are those they handled and write about in this book, while others were cases other doctors encountered, and share as coauthors in this book. Together, they illustrate the most frequent and complicated cases in refractive surgery and how different authors arrived at their solutions successfully.
The editors write in the Preface: “While most cases with successful outcomes have been included we have tried to illustrate in 101 cases how potential nightmares can have happy endings. We have simplified the process of analyzing the cases and extracting what is really the practical message that each case offers.”
Their process of case analysis is reflected in the systematic, step-by-step way they have laid out the content of this book, as we present to you below.
This book not only presents a large number of cases in refractive surgery, one for each its 101 chapters, its range of topics is also quite broad, as you can see from the titles of its nine Parts:
- Complications in Refractive Laser Treatment Plan
- Lasik Intraoperative Complications
- Lasik Early Postoperative Complications: Infection Complications and Sterile Complications
- Lasik Late Postoperative Complications: Dry Eye Syndrome, Epithelial Ingrowth, Corneal Ectasia, and Other Complications
- PRK Complications
- Corneal Inlays Complications
- Phaktic Intraocular Lens Complications
- Corneal Cross-Linking Complications
- Refractive Keratomy Complications
The content presented in each chapter is organized systematically, as shown below with, and under these headings:
- Chapter title
- Why Is this Case Relevant to the Refractive Surgeon?
- Case Background
- Main Problem to Solve
- Ancillary Tests
- Surgical / Medical Intervention
- What to Learn from This Case
Let’s take a look at chapter 7, Refractive Lens Exchange for High Hyperopic Astigmatism Followed by Lasik to “walk” through the step-by-step method the editors present a particular case to the reader, and how a successful outcome was arrived at.
The author Noel Alpins writes in the section Why Is This Case Relevant for the Refractive Surgeon? that complications can occur when the cornea and lens are not checked thoroughly:
“This case highlights some of the interesting complications resulting from an unrecognized low correlation between corneal and refractive lens values in a refractive lens exchange. A refractive lens exchange with a toric IOL was called for in this case. Although one would have expected the toric implant to correct for corneal astigmatism, subsequent excimer laser surgery (LASIK) was necessary.”
The author then presents the Case Backgroud: “A 47-yer-old male underwent an excimer laser surgery assessment with the hope of achieving a level of unaided visual acuity to enter the police force, which requires unaided 6/18 in better eye, 6/36 in other eye. He was found unsuitable for laser surgery due to a high amount of hyper-metropia and astigmatism in his subjective refraction. (A chart of results from an eye test is then presented).
In Main Problem to Solve, the author writes: “The high amount of astigmatism remaining postoperatively in the subjective refraction in both eyes was a refractive surprise.
Three choices are then presented and discussed in Options, and at the end of this section, the author writes: “The toric IOL was sitting at 18 degrees clockwise from its intended position of 168 degrees, resulting in a 2.25 D refractive cylinder postoperatively.”
This is followed by a discussion in Ancillary Tests, and in Surgical / Medical Intervention, the author writes: “LASIK surgery was performed in the left eye six weeks post IOL toric implantation and 16 weeks post IOL toric implantation in the right eye using the ViSX S4 system and the Amadeus (SiS) microkeratome.
In Outcome, the author writes: “Three months after LASIK surgery in the right eye and five months after LASIK in the left eye (eight months after bilateral toric IOL implantation) the patient was extremely pleased with the outcome!”
In What to Learn from This Case, the author writes: “It is important to calculate the ORA pre-surgery (using the iAssort software found on www.assort.com) to determine treatment possibilities, particularly LASIK or lenticular surgery which can remove the crystalline lens and lenticular astigmatism.”
This is an excellent and essential book for any student or practitioner of refractive surgery to own.
